LANXESS Offers New PBT and PC+PBT Blend for Vehicle Exterior Body Parts

LANXESS sees great potential for the use of PBT and polyamide compounds in production of vehicle exterior body parts – for example bumpers, sills, front grilles, door handles, fuel tank flaps, spoilers and mirror housings. “That is why we are building up a wide range of Durethan and Pocan materials for this use segment. The development work is focusing on application-specific, optimized mechanical properties, as well as good surface qualities and good paintability,” says Frank Krause, design expert at LANXESS.

New PBT for fuel tank flaps — suitable for CDC and dimensionally stable

An innovative material for fuel tank flaps, for example, is Pocan B 5220 XF reinforced with a glass bead content of 20 percent. The product is an alternative to blends of polyphenylene ethers and polyamide (PPE+PA), which are often used in series-produced fuel tank flaps because they can be painted online. A disadvantage of such blends, however, is their high degree of moisture absorption, which has an undesirable effect on the required dimensional accuracy. PBT, by contrast, stands out by virtue of its high degree of dimensional stability. “Our Pocan B 5220 XF also withstands the usual temperatures required for cathodic dip coating (CDC). That means the part can be mounted to the vehicle body and go through online coating and the CDC process along with it, which yields savings on logistics and coating costs,” adds Krause. Mineral-filled PBT and PA compounds, on the other hand, which fuel tank flaps are also made of, are not suitable for CDC. 

LANXESS has intensively studied the new material's thermal expansion behavior, using fuel tank flaps that were produced on a series-production tool. “Even after one hour at 200 °C the expansion of the freely suspended parts was negligible,” says Krause. Another strength of the new PBT is the good surface quality and paintability, which is due to the absence of glass fibers in the material. Compared to similar glass bead-reinforced standard materials, its much improved melt flow properties and the approximately 50 percent greater toughness are especially noteworthy. 


New (PC+PBT) blend for radiator grilles

LANXESS specially developed Pocan TP 406-001 for radiator grilles. “The non-reinforced polycarbonate+PBT blend material was conceived primarily for parts with Class A surfaces, which are given a high-gloss coating,” Krause says. The material displays very low and uniform shrinkage and hardly any tendency to distortion at all. Thanks to the blend's extreme toughness even in cold temperatures, the radiator grille does not shatter into shards in the event of a collision, which helps protect nearby pedestrians. The high heat deflection temperature ensures that long, horizontal grille fins do not sag as a result of exposure to the radiator heat. 

For exterior bodywork parts that are not coated online, the LANXESS product line continues to feature materials including non-reinforced (PBT+PC) and (PET+PC) blends, and reinforced (PBT+PET) blends. A good choice for spoilers, for example, is Pocan TP 957-001, which consists of up to 25 percent post-consumer recyclate from PET bottles. The mineral-reinforced (PET+PC) blend is very impact-resistant and displays minimal distortion, among other properties. Durethan DP 2131/20 W1 EF, a heat-stabilized polyamide 6 with easy flow characteristics, is a great material for substructures of spoilers, exterior mirror housings and door handles. It provides non-coated exterior bodywork parts with excellent resistance to weathering.

DSM’s Dyneema® UHMWPE Fiber Replaces Metal in Solar Panels to Provide Ballistic Protection

A new solar panel system for Defense Forces provides ballistic protection and is lighter and more portable than systems currently available. The PowerArmor™ unit from IDG Europe has low-reflectance solar panels protected by an anti-ballistic surface made in an exceptionally strong unidirectional fiber-reinforced composite.

The composite is based on an ultra-high molecular weight polyethylene fiber (UHMWPE) produced by DSM Dyneema and branded as Dyneema®, the world’s strongest fiber™. It replaces the aluminum normally used for portable solar panels, which provides no ballistic protection. IDG says this is the first time that solar panels have been given such a high level of ballistic protection. Panels made in Dyneema® also weigh around 20% less than aluminum panels of the same thickness.

DSM Dyneema and IDG Europe cooperated closely in IDG’s development of the dual-purpose system, intended to power electrical and electronic equipment used by armed forces in the field. The combination of ultra-light, low profile (anti-glare) solar panels and anti-ballistic panels with Dyneema® results in a system capable of providing energy and protection ranging from fragmentation to high-power rifle ammunition.

IDG Europe says that the switch from aluminum for the general-purpose stand-alone solar panels also meets calls from the market for lightweight units with high environmental resistance.

“As Defense Forces continue to carry more and more electronic systems into dangerous, inhospitable and isolated places, the need to keep portable electronic devices operable at all times in hostile environments is essential,” says Göran Johnson, CEO at IDG Europe. “With PowerArmor™, we think that we have a winning combination of solar panels that supply power and provide protection. We believe its chances are very good, especially as the two individual products were already being independently considered—and in some cases used in practice—by various Special Forces around the world.”

“Dyneema® offers the lightest armor protection materials in the market,” says David Cordova, Vice President Business Development for DSM Dyneema - Life Protection. “The combination of Dyneema® with the innovative low-glare IDG solar panels provides a unique value proposition to military personnel.”

IDG Europe introduced the PowerArmor™ concept at IESMA 2014, the conference and exhibition on Innovative Energy Solutions for Military Applications that took place in Vilnius, Lithuania, on November 12-14. IEASMA 2014 is organized by the NATO Energy Security Centre of Excellence, and the DELTA State Military Scientific Technical Center of the Ministry of Economy and Sustainable Development of Georgia.

Global Bioenergies Succeeds in Producing Bio-sourced Butadiene Using Fermentation

Global Bioenergies (Alternext Paris: ALGBE) announces having succeeded in the production of bio-sourced butadiene by direct fermentation. It is the first time ever an entirely biological production process -i.e. without any chemical step- is reported for butadiene, one of the most important petrochemical building blocks. 

Butadiene is a key platform molecule of the petrochemical industry with a world-wide market of over 10 million metric tons per year. As of today, butadiene is exclusively obtained from fossil resources, principally through extraction from naphtha cracking. Given the decrease in naphtha cracking capacities, there is a need for alternative routes to butadiene.

In this context Global Bioenergies has signed in 2011 a collaboration agreement with Synthos (Warsaw Stock Exchange: SNS), a leader in the production of butadiene-derived rubber products, to develop a direct fermentation route allowing a cost-effective transformation of renewable resources into butadiene. Since such a direct biological route does not exist in nature, Global Bioenergies first had to invent a new metabolic pathway comprised of a series of non-natural enzymatic reactions. This step was successfully achieved in December 2012. 

The next step consisted in improving the activity of those enzymes and implementing them into a bacterial strain. 

Global Bioenergies recently announced having created such a proprietary production strain. This strain was placed in a lab-scale fermentation device, and upon the addition of glucose, the presence of butadiene in the off-gases was detected. This is the first time ever that the production of butadiene by direct fermentation from renewable resources has been reported. 

Chief Technology Officer Frédéric Pâques comments: “We now have in our hands a prototype process for the direct biological conversion of renewable resources into butadiene. We expect that this butadiene program will deploy in the next years as did our isobutene process, our most mature asset now operated in an industrial pilot. Direct fermentation of butadiene has major inherent advantages translating into better economics. We expect to demonstrate these in an industrial environment in the next few years.” 

Jarosław Rogoża, R&D Director & Member of the Board at Synthos adds: “We have joined this program in 2011 when it was still in the discovery stage and are very glad it has since then followed the planned trajectory. We consider that the program is now significantly de-risked. We are looking forward to see how the program will behave in the next phase, dedicated to the optimization and scale-up of the process.”

DSM’s PA-based Tech. Results in Pressure Vessels Ideal for Lightweight Auto Fuel Tanks

Royal DSM, the global Life Sciences and Materials Sciences company, says a combination of two of its most innovative thermoplastics technologies has resulted in high performance pressure vessels that are ideally suited for use as lightweight fuel tanks for automobiles running on compressed natural gas (CNG) or hydrogen. With a solution for both the inner liner and the outer tape reinforcement, DSM is able to reduce the weight of the tank by up to 70%. 

Hydrogen and natural gas are claiming their place in the field of cost-effective and low carbon-footprint fuels for use in automobiles. Countries with major natural gas reserves are looking at the advantages of using CNG as an alternative fuel which reduces the CO2 emission by 15% compared to current solutions in petrol or diesel. 

A traditional steel tank of 40L weighs around 60 kg, while a composite ‘Type IV’ tank with Akulon® Fuel Lock liner can weigh down to 20 kg. Every 10 kg removed from a vehicle translates roughly into a reduction in CO2 emissions from the vehicle on the road of one gram per km.

Type IV pressure vessels are based on plastics and continuous fiber reinforcements, unlike Type I, II and III pressure vessels, which contain metal components. DSM demonstrated a tank with a liner blow molded in its Akulon Fuel Lock, a polyamide 6-based engineering plastic with very high barrier to hydrocarbons, at the Fakuma plastics processing exhibition in Friedrichshafen, Germany, in mid-October. The tank can be wrapped in a tape based on thermoset or thermoplastic resins, including its EcoPaXX® polyamide 410. 

Liner material for the CNG tank

Akulon Fuel Lock contains an additive formulation that further improves the already strong gas barrier of polyamide 6, and also provides it with extremely high impact resistance at low temperatures (down to -60°C). The permeation of HDPE liners is too high to allow the installation of composite Type IV tanks incorporating such liners inside a vehicle. However, Akulon Fuel Lock liner material reduces emissions by a factor of at least 150 compared to HDPE and therefore enables the use of Type IV tanks inside the car.

The Akulon Fuel Lock portfolio has been expanded with a grade that is suitable for blow molding of liners for large pressure vessels for heavy duty vehicles such as buses and trucks. It is normally difficult to make large blow moldings in polyamide 6, owing to the polymer’s relatively low melt strength, but this grade has sufficient melt strength to create a stable parison for tanks beyond a length of 2m, enabling high precision in control of the wall thickness.

Tape material for CNG tank

In current Type IV pressure vessels, the tape reinforcement comprises either glass or carbon fibers in a thermosetting polymer, such as an epoxy or unsaturated polyester. DSM is cooperating in the development of next-generation Type V pressure vessels. These are made by winding a tape, developed by DSM, of continuous fiber reinforced with a thermoplastic, such as the company’s EcoPaXX polyamide 410, or another grade of Akulon.

Type V pressure vessels weigh around 70% less than steel tanks and can be lighter than Type IV pressure vessels too. They are more durable than steel, they have better chemical resistance (no corrosion), and they are also fully recyclable. EcoPaXX has the additional advantage that it has a zero carbon footprint from cradle to gate, owing to the fact that the polymer is made entirely from renewable resources.

“In the process developed by Covess for making Type V pressure vessels, you can balance weight, performance, and economics by using glass, carbon or even hybrid fibers,” says Tony Vanswijgenhoven, Director of Covess, a specialist in advanced thermoplastic composite vessels for a wide range of applications, who is working closely with DSM. “Whatever choice you make, it always works out lighter than the existing comparable type IV tanks.”

Dassault Systèmes and Solar Impulse define a new chapter in the future of solar-powered aviation

The Solar Impulse 2 airplane, revealed on April 9 and successfully test flown in June of this year, is designed using Dassault Systèmes’ 3DExperience platform.

Solar Impulse uses Dassault Systèmes’ 3DExperience platform, including its Catia and Enovia applications, to design, build, and validate this second solar airplane. Solar Impulse 1 was a test bed for the incredibly complex new technologies required to fly day and night using solar energy alone. Solar Impulse 2 will carry the mission forward and fly around the world in 2015.

The team faced new challenges and trade-offs in designing such an innovative plane, including a new design for the fuselage and wings, and using new materials to achieve strict weight objectives. Designing a cockpit providing safety, comfort, and command accessibility for a pilot on an around-the-world flight required sophisticated design and management tools. Dassault Systèmes applications, in use by the team since 2006, helped ensure smooth execution of the ongoing development process and milestones.

“For over a century, pioneers have been pushing the limits of aviation and transforming ideas into ‘firsts,’ from the first human flight to balloon flights and space missions once thought to be impossible,” said André Borschberg, Co-founder CEO and Pilot, Solar Impulse.  “We continue to apply this entrepreneurial spirit to engineering and research programs that blend 21st century technologies like the 3DExperience platform with a mission to improve mankind’s impact on the environment.”

Verdezyne & Bio-XCell to Set-up First Biobased DDDA Production Facility in Malaysia

Verdezyne, Inc., a privately-held industrial biotechnology company focused on producing renewable chemicals, recently announced it has reached an agreement with Bio-XCell Malaysia to construct Verdezyne’s first commercial-scale renewable chemicals manufacturing facility in Bio-XCell’s premier biotechnology and ecosystem park in Nusajaya, Iskandar, in southern Malaysia. With construction scheduled to commence in 2015, the plant will be capable of producing approximately 30 million pounds per year of diacids, including dodecanedioic acid (DDDA), and will be the world’s first bio-based plant for the production of DDDA. 

The exchange of agreement ceremony took place during the official opening ceremony of “BioMalaysia: Bioeconomy Asia Pacific 2014 Conference & Exhibition,” and was attended by Malaysian Prime Minister Najib Razak. 

“This agreement is part of our comprehensive strategy of expansion into Asia, and represents a huge step toward our goal of replacing petroleum-derived chemicals with renewable drop-in replacements,” commented E. William Radany, Ph.D., President and CEO of Verdezyne. “We are thrilled, and are eagerly anticipating breaking ground in the near future on this major new manufacturing plant for the production of renewable diacids.” 

The multi-faceted agreement includes: 
• Leasing a 6.9-acre site owned by Bio-XCell in Malaysia’s premier biotechnology park located in Nusajaya, Iskandar, Malaysia, 30 minutes’ north of Singapore. The 13-year, renewable lease provides for expansion options on other adjacent lots, and all major utilities will be supplied by Bio-XCell. 
• A loan of approximately $75 Million (approximately RM 250 Million) from Bio-XCell. 

“We are happy to welcome Verdezyne to the Park. The investments related to building Verdezyne's new factory here will bring the total investment into Bio-XCell to RM250 million, and with a couple more companies in the pipeline, we expect to have secured RM1.86 billion [approximately $555 Million] in investment by year-end. The investments will further augur and strengthen the value proposition of the Bio-XCell ecosystem as a regional hub for industrial biomanufacturing and bioprocessing,” said Rizatuddin Ramli, Chief Executive Officer of Bio-XCell Malaysia. 

“We are proud of our successes with our Malaysian partners, who recognize the strong value proposition we bring to the table,” added Dr. Radany. “To review, in June of last year we reached a collaboration agreement with Malaysian Biotechnology Corporation, and in September of last year we were awarded BioNexus Status by the Malaysian government. In April of this year we secured $30 Million in financing from Malaysian conglomerate Sime Darby, and our signing ceremony was attended by none other than President Barack Obama. As rewarding as our projects in Malaysia have been thus far, though, we feel that the best is yet to come.” 

The manufacturing facility will leverage Verdezyne’s yeast fermentation technology with the abundant supplies of non-food, plant-based feedstocks in Malaysia to produce a variety of commercial diacids, including DDDA. These diacids may in turn be used to produce nylon or other polymers for use in a variety of applications including: engineering resins, automotive parts, athletic apparel, carpeting and toothbrush bristles, at lower cost than traditional, petroleum-derived nylons.

KRAIBURG's Medically-compliant TPE Finds Application in Single-use Membrane Valve

Cross-contamination must be eliminated in valves used for sensitive pharmaceutical process technology. The safest method is to use one-way valves, which until now has meant replacing the entire valve. With its controlled single-use membrane valve GEMÜ SUMONDO®, with a special TPE membrane from KRAIBURG TPE, GEMÜ is introducing a safe and cost-effective system. With it, only the valve unit has to be replaced, because thanks to the interior membrane, it is the only part that comes into contact with the pharmaceutical media. The actuator itself remains in the system for re-use. The valve unit, which is manufactured in a cleanroom out of sterilized polypropylene, is equipped with a TPE membrane. The ultrasonically heat-sealed membrane hermetically separates the media from the environment and from the valve's actuator. Moreover, it also regulates the volume flow in the valve during operation. 

"Using THERMOLAST® M, the medically-compliant TPE from KRAIBURG TPE, represents a fundamental contribution to our new development. The elastic properties, together with the extensive chemical stability in conjunction with the Medical Service Package, are contributing to this progress," says Valentin RÜttimann, Product Engineer for single-use systems at GEMÜ, on the first collaboration between the two companies. 

A microbe-proof barrier with THERMOLAST® M

THERMOLAST® M has also generated interest thanks to its simple, time-saving, and cost-effective manufacturing process with polypropylene. This processing method enables short cycle times and makes post-processing the component unnecessary. In addition, the procedure makes it possible to create a microbe-proof barrier. THERMOLAST® M allows direct contact with a pharmaceutical medium or blood. It has comprehensive medical certifications (USP Class VI, USP 661, DIN ISO 10993-4 "Haemolysis, Indirect in Human Blood", ISO 10993-5 "Cytotoxicity", ISO 10993-10 "Intracutaneous Irritation", ISO 10993-11 "Acute Systemic Toxicity"). 

The Medical Service Package

KRAIBURG TPE ensures product reliability and safety for all of its THERMOLAST® M materials as part of its Medical Service Package. The compounds from the medically-compliant portfolio are manufactured on a separate production system. There, only materials that correspond to the requirements of the medical industry are used, and contamination with other products or parts, such as raw materials of animal origin, is eliminated. For this quality assurance in the medical and pharmaceutical technology industry, KRAIBURG TPE guarantees composition consistency and security of supply for two years.

DuPont's Renewably-sourced Sorona® EP Polymer Finds Use in DTR's Cervical Biopsy Punch

DTR Medical, among the leading manufacturers of single-use surgical instruments, has specified Sorona® renewably sourced polymer for six components in its new Cervical Rotating Biopsy Punch. This grade is a 15-percent glass filled grade of Sorona® EP providing high strength and stiffness. Further attributes of Sorona® useful in this application include resistance to gamma sterilization and excellent dimensional stability.

The Cervical Rotating Biopsy Punch is used to take a tissue sample, on patients undergoing cervical cancer biopsies, for cell analysis by microscopy. The DuPont material, which is supplied with full regulatory compliance for use in healthcare applications and is produced according to Good Manufacturing Practices (GMP) standards, is used in the handle and trigger mechanism to mold the rear hand left and right, front handle, connector pin, rotational controller and the rotational controller with chamfer. These parts are used to activate a spring, driving the inner rod which, assisted by the Sorona® inserts, generates a clamping force to cut the tissue sample.

The Cervical Biopsy Punch with Rotation from DTR Medical is designed for single-use, which eliminates cross contamination that occurs when re-using hard-to-clean instruments and saves considerable time and cost incurred by sterilizing the equipment for re-use.
According to Andrew Davidson, Managing Director at DTR Medical: "The surface finish of the handle is fundamental for instrument quality, replacing stainless steel and for good grip in the clinical setting. The part must deliver durable mechanical performance in use throughout the five year shelf life and the benefit of renewably sourced material is an added advantage for a single-use manufacturer. We tested many polymers for these components, and the DuPont material was superior."
Glen Wells, General Manager at St Davids Assemblies added: "Sorona® EP from DuPont combines the benefits of renewability with processing and performance advantages. The material can be processed similarly to PBT and PET, offers very low shrinkage and warpage, enhanced surface finish, and scratch resistance in finished parts." Sorona® contains 20% to 37% renewable material made with a renewably sourced propanediol (PDO) made from technical starch.

Lehvoss Unveils High Performance LUVOCOM® 70 PK Compounds for Engineering Applications

Lehvoss North America announces the introduction of its LUVOCOM® 70 series of high performance compounds based on polyketone (PK). These compounds fill the gap between compounds based on technical polymers like PA6PA66, and acetal and high performance polymers such as polyphenylene sulfide (PPS), polyetherimide (PEI), and polyaryletherketone (PAEK). In having a combination of select features of these other polymers, the PK polymer offers an exceptional property profile with unique advantages for applications having multiple engineering requirements.

"The introduction is actually a re-launch," explained Michael Sandeen, Sales and Business Development Manager at Lehvoss, "Various LUVOCOM 70 products had been available until the year 2000 but had to be cancelled due to Shell Chemical's discontinuation of Carilon PK polymer production. With the polymer now available, Lehvoss decided to start the development of these new high performance compounds because of their unique and outstanding properties."
With its unique profile, PK polymer is a multi-use material that offers inherently good tribological performance. "In many cases it is better than acetal and polyamides (PA)," said Sandeen. "It can replace even high temperature resistant polymers in tribological applications." PK also offers good hydrolytic stability, low permeability, good weld line strength, and good processability with shorter cycle times compared to other technical polymers such as PA 66 and acetal.
"The polymer's low wear rate offers excellent advantages for gear wheels and bearings," said Sandeen. "Its low water absorption makes it suitable for applications where parts come in contact with moisture, and its high level of chemical resistance makes it suitable for applications such fuel filters and other fuel system components. Its chemical resistance together with its mechanical properties and tribological performance makes it particularly suited for stock shapes and seals."
The LUVOCOM 70 line consists of three grades: 70-9045 reinforced with carbon fibers; 70-9046 lubricated with PTFE, and 70-9113/BK formulated for low wear and friction. Lehvoss will also develop made-to-measure compounds based on customers' needs.

BASF's New Elastollan® AC 55D10 HPM TPU Finds Application in Citroën C4 Cactus' Airbumps

As a manufacturer of thermoplastic polyurethane (TPU), BASF has successfully optimized the material so that it can be applied extensively and unpainted on the vehicle exterior. The automotive manufacturer PSA Peugeot Citroën uses the new TPU grade Elastollan® AC 55D10 HPM (High Performance Material) for cladding the Citroën C4 Cactus with so-called Airbumps®. These are large air-filled cushion bumpers in contrasting colors: They are fitted on the sides as well as on the front and rear of the vehicle, protect the car exterior from impact and scratches and give the vehicle its distinctive look. This world first is the result of many years of development work between the French automotive manufacturer, the supplier Rehau, Switzerland and BASF. Rehau manufactures the side Airbumps®, while the company Faurecia, France produces the bumpers at the front and back.
"With their characteristic Elastollan® surface, Airbumps® embody the philosophy of the Citroën C4 Cactus perfectly — they have style and are multifunctional. Together with BASF and the suppliers of the Airbump® parts, we have shaped material development and the manufacturing process in such a way that the two have resulted in models offering the optimum combination of quality, aesthetics and costs", explains Jérôme Vinot Préfontaine, Purchasing General Manager for the C4 Cactus program at PSA Peugeot Citroën. The advantage of Elastollan® HPM lies in its freedom of design and long-term durability together with attractive haptics and a high-class appearance. The new material combines the properties of conventional TPU, such as good tensile strength and abrasion resistance, elasticity, excellent impact resistance at low temperatures and high media resistance, with new features: It has outstanding surface properties even at low wall thicknesses, it is scratch-resistant, UV- and weather-resistant, is easy to clean and has a high service temperature of 120 to 150°C.

Good assembly properties

This makes it an ideal surface for the impact-absorbing Airbumps® which give the C4 Cactus its characteristic graphic looks. The injection-molded Elastollan® component is mounted to a polycarbonate and acrylonitrile-butadiene-styrene (ABS) support shell, thus forming flexible cavities that can be dented and bounce back again. The entire structure is fixed to the metal chassis. Because of the good mounting properties of the HPM grade a tight assemblage is possible which conventional trim materials such as polypropylene do not achieve.
Elastollan® HPM can be pigmented, so the Airbumps® do not have to be painted. Thus, they do not require any special maintenance and in case of an accident help reduce the repair costs for the vehicle. The bumpers are available in four contrasting colors (black, brown, light and dark gray) and contribute to the harmonious individual color design with the automotive coatings, primers and clearcoats from BASF's Coatings Division.

Processing: short cycle time and good flow properties

BASF has also further developed the processing properties of the new Elastollan® grade. The material can be injection-molded within a wide process window with a cycle time that is 50% shorter compared with conventional TPU. It has excellent flow properties, which means that low wall thicknesses of 1.5 to 1.8 mm can be produced without affecting the surface quality. "Because of the high demands on surface and color, hardness and flexibility the close cooperation with BASF in material formulation and application development was a decisive factor for us", explains Bernard Delles, Project Head at the automotive supplier Rehau which manufactures the side Airbumps®. Faurecia uses the new Elastollan® HPM for manufacturing the bumpers at the front and back of the C4 Cactus. "The innovation lay not only in the material but also in the mounting. BASF has developed a plastic that required a new assembly technology. We worked closely to meet the requirements for the industrial mass production of these unusual parts", says Sébastien Bret, Development Manager at Faurecia.
Up to now, Elastollan® has been used in the automotive industry as cable sheathing, in the engine compartment and in the vehicle interior, e.g. for door handles, gear knobs and cupholder linings. BASF's TPU can be injection-molded, extruded or blow-molded.

LANXESS Achieves Process Innovation in Production of Tepex Continuous FRT Composites

LANXESS has achieved a process innovation in the production of continuous fiber-reinforced thermoplastic Tepex composites. The subsidiary company Bond-Laminates, which manufactures these composites, is now able to continuously series-produce large semi-finished composite products in which the continuous fiber layers can be oriented at almost any conceivable angle. Until now, the continuous fibers in Tepex could only be lined up in the direction of production or perpendicular to it (0 degrees or 90 degrees). This process innovation means the designer can use the differently oriented composite continuous fibers to help him react more specifically to the force transmission in the target component. Even quasi-isotropic constructions can now be fashioned using Tepex. "This means Tepex can be used to design lighter-weight composite components that are tailored even more specifically to the load in question. So the new-generation Tepex strengthens our position as a leading supplier of thermoplastic high-performance composites for lightweight design," says Dr. Dirk Bonefeld, head of Research and Development at Bond-Laminates.

Suitable for large-scale series production with minimal waste

These multiaxial Tepex semi-finished products are fully impregnated and consolidated. Despite being formable to quite extreme angles, their impregnation means the fibers are unlikely to slip. As in the past, Bond-Laminates will consult closely with the customer regarding cutting the semi-finished products into pre-contoured profiles for forming and overmolding or compressing. Special nesting programs help keeps wastage to a minimum in almost all cases. "Thus the processor receives a fully constructed, made-to-measure composite material that can be shaped into highly load-resistant, complex components in very short cycle times without generating wastage," says Bonefeld.

Unidirectional properties

Thanks to the continuous fibers' high degree of orientation, the individual fiber layers demonstrate almost unidirectional properties. The stiffness and strength of the individual layers based on polyamide 6 and continuous glass fibers are 37 GPa and 780 MPa respectively in the direction of the fibers.

Broad spectrum of applications

Their high-quality mechanical set of properties, which can be tailored to meet specific requirements, makes multiaxial Tepex semi-finished products the perfect material for manufacturing high-strength structural components and semi-structural components for automobiles in particular. "For example, we are currently working on front end carriers, pedal and seating components, carriers for electrical and electronic modules, engine compartment guard plates, airbag housings and components used in underbody protection. We are also looking at components that require custom construction for meeting a combination of torsional and flexural load requirements," Bonefeld adds.

DSM's Dyneema® UHMWPE Fiber-based Fishing Trawls Improve Sustainability of Fishing Industry

Fishing Company Cornelis Vrolijk, based in IJmuiden, The Netherlands, and its subsidiary Jaczon, based in Scheveningen, The Netherlands, are specialized in pelagic fishing. The fishing trawls on board of their trawlers, which are used for catching pelagic (schooling) species, are traditionally made of nylon. Cornelis Vrolijk and Jaczon are now replacing their nylon trawls by trawls made from DSM's light and exceptionally strong UHMwPE (ultra high molecular weight polyethylene) fiber, branded as Dyneema®.
The use of this far thinner material in pelagic trawls offers immediate and tangible environmental advantages. The reduced resistance of the trawls in the water translates into a significant reduction in CO2 emissions, thus reducing the CO2 footprint of the pelagic fishing fleet. In this way Dyneema® makes a substantial contribution to improving the overall sustainability of the fishing industry.

The innovative trawls made from Dyneema® were developed by Maritiem BV in Katwijk, The Netherlands, in close consultation with DSM. Around 90% of the trawl material is Dyneema®. During both the design and use of the trawls, Maritiem worked closely with the relevant departments of both fishing companies and with the officers on board the vessels.
Dyneema® fiber is used in hand-spliced front sections of the trawls, from mesh size 800 mm and up. According to Maritiem some of these sections were previously made of knotted netting, but the knots were prone to slip. This does not happen with hand-spliced trawls. Dyneema® can be used for these sections. Dyneema® is also used for the selvedge lines and the frame ropes.

In order to allow for a proper comparisons, identical trawls made of predominantly conventional materials such as nylon, were also carried on board some of the vessels. This made it possible to compare the performance of the different materials used in trawls of an identical design. The fishing company's assessment of the new trawls was extremely positive.
Eric Roeleveld, Operations Manager of Jaczon says: "As a company specialized in pelagic trawling, we are profoundly aware of the environmental impact of our activities. One of our key drivers is to continuously look for increased sustainability in our fishing methods. We try to reduce our CO2 footprint wherever possible and support the FAO code of conduct for sustainable fisheries."
Cornelis Vrolijk and Jaczon now have eight of the trawls made with Dyneema® in use. The size and shape of the trawls depends on the targeted species, fishing area and the dimensions of the vessel.
The newly developed trawls offer a number of specific benefits in comparison to traditional nylon versions. The lighter material makes them easier to handle and therefore safer in use for the crew.

Feedback on the new fishing trawls has been favorable: "Positive results are coming in from all quarters." says Johan Müller, Cornelis Vrolijk's Fishing Fleet Manager, "We can also confirm a substantial reduction in fuel consumption and subsequent CO2 emissions."
As well as easier, safer use and savings on fuel, the development of lightweight fishing trawls has brought about a major improvement in sustainable fishing techniques. "This is good for the environment and good for the fishing industry." says Johan Müller. "We would definitely encourage other fishing companies to adopt this strategy and the use of this new material as well."

Braskem Provides Sugarcane Ethanol Derived Green PE-based Packaging for Organic Bread

Eureka! Organic Bread is introducing three bread varieties on the East Coast. The new flavors are certified Vegan and USDA Organic, and the renewable bag demonstrates the company's commitment to sustainability. Braskem and Bimbo packaging engineers have been working to produce bio-based packaging using Braskem's Green Polyethylene, which is produced from sugarcane ethanol, a 100 percent renewable raw material. The sugarcane used is non-GMO (genetically modified organisms) based. The bread packaging is made with 36 percent bio based material; verified using ASTM D6866, Eureka! Organic Bread bags are the first packaged bread in North America to use this renewable and sustainable technology.
For each ton of plastic produced, green plastic sequestrates approximately 2.15* tons of CO2 from the atmosphere. To help consumers recognize green plastic in stores, Braskem created a seal, which guarantees the renewable content of the plastic.

Braskem has been making Green Polyethylene since 2010 at its Triunfo Petrochemical Complex, in the state of Rio Grande do Sul, in the south region of Brazil. The plant's capacity is 200 kton/year and the total investment amounts to US$290 million.

Momentive's Lightweight CF Epoxy Door Structure Wins SPE's ACCE's 'People's Choice' Award

Momentive Specialty Chemicals Inc. ("MSC") won the "People's Choice" Award for the "Most Innovative Composite Part" at the annual Society of Plastics Engineers Automotive Composites Conference & Exhibition (ACCE) last month in Novi, Michigan. The lightweight carbon fiber epoxy door structure submitted by MSC was singled out by vote of conference attendees.
Judging for the competition was based on the impact and trendsetting features of each application, including construction materials, processing methods, assembly methods, and other technologies that made the application possible. Design benefits, weight and cost reduction, parts consolidation, functional integration, and improved performance were also taken into consideration.

The winning component was a light-weight, carbon fiber epoxy door and window frame profile produced by Benteler-SGL for 2013 and later Porsche 911 GT3 Cup coupes. The composite was manufactured by high pressure resin transfer molding (HP-RTM) using MSC's EPIKOTETM 04695-1/EPIKURETM 05357 epoxy resin system, carbon fiber (Sigrafil® type C40 supplied by SGL Group) and polyester fiber. The component's Class A surface was finished in the body color.

Innovative features of this part include a simplified, integrated 2-piece design with a single structural inner piece incorporating the header, and a Class A outer panel. The door is a light-weight, trimmed body structure weighting 5.5 kg, compared to 15.0 kg for the standard series door. The raw body of the door weights 4.0 kg and the polycarbonate window and paint weight 1.5 kg. The inner and outer shells are manufactured via HP-RTM, and the outer shell is designed as a "micro-sandwich" to achieve the requisite buckling strength and performance at the minimum weight.
Design benefits of this MSC epoxy resin composite part are: a greater than 60% weight reduction, compared with metal; lower vehicle center of gravity; Class A appearance; and short cycle-time production. The HP-RTM process is set up in automated steps, accommodating build rates from low volume (500 pieces/year) to high volume (up to 100,000 pieces/year) with a fully automated process line.

Braskem, Amyris & Michelin Collaborate to Develop & Commercialize Renewably-sourced Isoprene

Amyris, Braskem and Michelin announced recently that Braskem is joining a collaboration already launched in 2011 between Michelin and Amyris. This collaboration was initiated to develop and commercialize renewable isoprene, sourced from various biomass as an additional sustainable pathway to produce isoprene.
Under the terms of the agreement, Braskem, Michelin and Amyris will work together to develop a technology to utilize plant sugars, such as those found in Brazilian sugarcane or cellulosic feedstocks, to produce renewable isoprene. Adding the expertise of Braskem, the largest petrochemical company in the Americas and one of the global leaders in the production of biopolymers, Amyris and Michelin will accelerate the industrialization of renewable isoprene.
Amyris will share its rights to commercialize the renewable isoprene technology developed under this collaboration with Braskem. Michelin will maintain certain preferential, but not exclusive, access to the renewable isoprene to be produced by this technology. The companies will not disclose details of the agreement, including the financial contributions of each party.

This joint project, with Amyris and Braskem, will give Michelin an additional sustainable sourcing channel for poly-isoprene for the production of quality tires, providing a high-performance, environmentally responsible material.
“With this new partnership, we join forces with Amyris and Michelin in the development of an innovative technology that strengthens our commitment to improve people’s lives, creating solutions through sustainable chemistry,” said Luciano Guidolin, Vice President for Polyolefins and Renewables of Braskem.

DSM Unveils Dyneema Purity® Radiopaque UHMWPE Fiber for Devices Used in Orthopedic Trauma

DSM, among the global leaders in biomedical materials science and regenerative medicine, announced the launch of its Dyneema Purity® Radiopaque fiber, one of the radiopaque ultra-high-molecular-weight-polyethylene (UHMWPE) medical fibers in the world. The fiber is the newest addition to DSM's medical Dyneema Purity® fiber portfolio.
Dyneema Purity® Radiopaque fiber is designed to support the development of medical devices for use in orthopedic trauma. The fiber contains a radiopacifier, which makes it the only UHMWPE fiber currently available that is visible in x-ray images. This feature helps surgeons with medical device and implant visualization both during and after surgical interventions.

The fiber will initially be used as a replacement for metal surgical cables that are used in procedures to treat bone fractures. The fiber is 15 times stronger than steel but maintains high pliability and increased flexibility, which may help lower the risk of bone damage. Steel does not conform well to the natural contours of the human body. A small contact point between the bone and metal wire leads to high levels of pressure in a concentrated area during surgery. On the other hand, UHMWPE fibers conform directly to complex bone anatomy, which increases surface contact and spreads force more evenly, reducing the risk of the cable cutting into the bone. The fiber is biocompatible and chemically inert, which can help reduce tissue inflammation, irritation and complications associated with metal allergies. All of these factors can increase patient comfort and promote shorter healing times.

UHMWPE fiber has additional advantages for cable construction. If a steel cable is wrapped around portions of a bone that require repairs, both ends of the cables must be guided through a tensioning device. Once fixation is complete, no incremental adjustments are possible and a re-adjustment can only be accomplished by cutting the cable and starting all over again. In contrast, a cable construction made from UHMWPE fiber promotes more flexibility and allows for re-tensioning after primary fixation without the need to start from scratch.
"With its impressive durability, flexibility and X-ray visibility, our Dyneema Purity® Radiopaque fiber gives device manufacturers the opportunity to use UHMWPE fiber in new applications," said Carola Hansen, Director of Biomedical Polyethylenes, DSM Biomedical. "Creating quality and innovative materials that help patients and surgeons is of the utmost importance to DSM."
"As an orthopedic surgeon, I have firsthand knowledge of the current challenges presented by traditional, steel cable solutions," said Professor Dr. Lodewijk van Rhijn, head of the department of orthopedic surgery at the University Hospital Maastricht, The Netherlands. "DSM's new Dyneema Purity® Radiopaque fiber has high flexibility which has the potential to reduce the chance of patients suffering from neurological damage. Further, the radiopacity would allow me to check instrumentation stability using x-ray imaging." Dyneema Purity® Radiopaque fiber is available worldwide.

Biopolymer & PHA Producer Meredian Receives Investment from Perry- McCall

Meredian Inc., a privately held biopolymer manufacturer and one of the world's largest producers of PHA (polyhydroxyalkanoate), announced the receipt of an investment from the world class engineering and construction group, Perry-McCall. Prior to this investment decision, the group was selected and is currently building out Meredian's manufacturing facility to produce the completely biodegradable plastic.

"As part of our validation of proof of concept and business model we addressed scalability with Tate and Lyle and modularity and buildout with Perry Mcall. Our model has been validated every step of the way by third party credible professional organizations," said Paul Pereira, Executive Chairman to the Board of Directors at Meredian Inc. In August 2013, the Engineering and Construction Group of Perry-McCall started working with the Engineering and Process Development Group at Meredian to create the design for the facility. After eight months of studying the process and working on the design, the internal group of Perry-McCall approached their President, Wayne McCall, about investing their own personal money in the project. After the preliminary design was completed in April, the engineering and construction company approached Meredian's Executive Chairman, Paul Pereira regarding their desire to invest.

"We are extremely excited about the project, because they have found a way to clean up landfills," said Wayne McCall of Perry-McCall. "While it takes between 500-1000 years for petroleum to break down, these bioplastics only take 5-6 weeks. The environmental and economic impacts are huge, and for us being design contactors, the product Meredian produces can develop more business for us."

Meredian's innovative biopolymer is at the leading edge of unparalleled advancement in the Bioplastics field, which they presented at the 9th Annual Biopolymer Symposium in May. Some of the recent accomplishments include gaining the FDA approval for Food Substance Contact, harvesting the first crop of canola to be used to create the PHA and partnering with the global provider Tate and Lyle to demonstrate the ability for Meredian's product to be manufactured on a mass scale. Additionally, they have also received four certifications and two statements from Vinçotte International confirming their PHA formula is completely biodegradable in six different mediums. They are the only biopolymer manufacturer in the world that has received certifications of biodegradability in anaerobic, soil, freshwater, marine, industrial composting and home composting.

In addition, Dr. Isao Noda, Chief Science Officer at Meredian has just been awarded a Professorship at Peking University, one of the most prestigious Universities in China.

McCall believes the supportive move is a "Win, Win" due to the fact the company has more investment dollars and the engineering group has an even greater reason for the project to come in under budget and ahead of schedule.
