Circa Receives ECHA Approval for Bio-based Di-polar Solvent Manufacture

Circa Group has received authorization from the European Chemicals Agency (ECHA) to manufacture or import up to 100 tones/year of its bio-based solvent Cyrene™ in the European Union, after receiving REACH Annex VIII approval.

Cyrene™ : An Alternative to Polar Aprotic Solvents

 A chiral dipolar aprotic solvent, Cyrene™ was developed in conjunction with the Green Chemistry Centre of Excellence (GCCE) at the University of York. Cyrene™ is a two-step conversion of waste biomass, produced at Circa's large-scale prototype plant, built in partnership with pulp and paper company Norske Skog in Tasmania, Australia.

Cyrene™ provides a safer alternative to these polar aprotic solvents facing regulatory pressure worldwide and is available through Circa’s distributors Merck/Sigma and Will&Co.

Restricting the Possible Toxic Solvents

Solvent regulation is increasingly focused on restricting hazardous chemicals to manage their risk to people animals and the environment. In the EU, widely used solvents such as NMP, DMF and DMAc are on the candidate list of Substances of Very High Concern (SVHC) due to their reprotoxicity.

In addition, a new restriction on NMP was adopted earlier this year, meaning that after May 2020, use will be further restricted and it will not be able to be manufactured or used in the EU unless operational conditions are maintained to ensure that exposure to workers is below specified levels.

Crossing a Major Milestone

Tony Duncan, CEO and co-founder of Circa Group, said, "Annex VIII authorization is a major milestone for Cyrene™ and we are delighted to have been given the go-ahead to sell Cyrene™ in significantly larger quantities in Europe.

Safer solvents are urgently required and with Cyrene™, we are also offering a bio-based solution with a unique property set, including viscosity, surface tension and polarities – making it an exciting new prospect for advanced materials. Our next goal is registration of Cyrene™ in the US and other jurisdictions will soon follow.”

Sulzer Enters into Partnership to Promote PLA-based Sustainable Plastics Production

Futerro, Sulzer and TechnipFMC team up to simplify the manufacture of bioplastics. Three major process technology and equipment specialists, Futerro, Sulzer and TechnipFMC, have formed the PLAnet™ initiative in equal partnership to promote the production of sustainable plastics made of Poly-Lactic Acid (PLA). The strategic collaboration will support manufacturers interested in entering the bioplastic market by delivering integrated PLA technology packages.
PLA is a versatile bio-based and biodegradable polymer that can replace petroleum-based plastics in a wide range of applications. Different stages are required to convert sugars from crops into lactic acid, lactide and subsequently PLA.

Facilitating Bioplastics Production

Futerro, a well-established technology provider for lactic acid and lactide production, and Sulzer Chemtech, a leading specialist in separation and mixing technologies have over 25 years of experience in lactic acid and PLA’s related processes. Together they have further shown their commitment to facilitate the production of bioplastics by establishing a partnership with TechnipFMC, a leading global EPC contractor with experience in technology development and licensing with fast growing activities in bioplastics and green chemicals.

PLAnet™ Initiative 

The agreement between the three parties offers to agricultural, chemical and fiber industries, a fully integrated package addressing the whole PLA value chain. In this way, customers can benefit from direct access to state-of-the-art, customizable solutions for all the aspects and stages of PLA production. PLAnet™ offers the possibility of a “one-stop shop” for customers interested in PLA production by providing a single point of contact and responsibility.

Goal of PLAnet™

In particular, PLAnet™ supports the construction of plants of any size, including PLA facilities with a throughput of up to 100’000 tons per year - that permit manufacturers to save both capital expenditures (CAPEX) and operating expenses (OPEX) by providing for integrated and optimized plant section design.
Within the PLAnet™ partnership, Futerro’s proprietary technology focuses on the production of lactic acid and raw lactide from sugar or, directly, from biomass; Sulzer contributes the process for the purification of lactide and its polymerization to obtain PLA while TechnipFMC acts as technology integrator to deliver seamless and optimized Front-End Engineering Design (FEED) packages.
The promotion of greener alternatives to traditional plastics needs to be backed by suitable technologies that enable the industry to produce high-quality bioplastics in an efficient manner. This can be made possible via the PLAnet™ partnership between Futerro, Sulzer and TechnipFMC by leveraging their world-leading technologies, expertise and skills for the entire PLA value chain.

Plastics Machinery Shipments Continued to Increase in Q3 of 2018 in North America

 The plastics machinery shipments in North America continued to increase in the third quarter according to the statistics compiled and reported by the Plastics Industry Association’s (PLASTICS) Committee on Equipment Statistics (CES).

 

 

Injection Molding & Extrusion Machinery Shipment

The preliminary estimate of shipments of primary plastics equipment (injection molding and extrusion) for reporting companies totaled $349.4 million in the third quarter. This was a 4.1-percent increase from the $335.5 million (revised) second-quarter shipment. Injection molding shipments in the second quarter were higher than previously thought. Year over year, shipments grew 5.6 percent.

Perc Pineda PhD, Chief Economist of PLASTICS, said:
“Plastics machinery shipments recovered in the third quarter following a weak second quarter. We expect higher shipments in the fourth quarter. We have a tight labor market and U.S. manufacturers, including plastics machinery manufacturers, have been working on production backlogs. As a result, shipments are pushed into the next quarters.”

Quarterly Statistics

• On a quarterly basis, injection molding shipments increased 2.1 percent. Single-screw and twin-screw extruder shipments continued double-digit growth of 23.8 percent and 14.2 percent, respectively. 
• Compared to the third quarter last year, shipments of injection molding were up 4.6 percent. Shipments of single-screw extruders rose 7.7 percent and twin-screw extruders 17.2 percent over the same period.

Perc Pineda said:
“Except for soft auto and home sales numbers in the third quarter, the U.S. economy is still in expansionary mode—and that’s good news for plastics machinery manufacturing. While there are projections of moderate growth next year, it is expected that the U.S. economy will remain healthy.”

California Bans Sale of Upholstered Products Containing FRs Above 1000ppm

California has joined states to ban flame retardants in certain household products. Starting January 1, 2020, it will be prohibited to sell or distribute children’s products, mattresses, and upholstered furniture that contain flame retardants in concentrations above 1,000 parts per million (ppm) in the state of California.

Link Between Flame Retardants and Various Health Problems

 In passing the bill, the Legislature cited proof that flame retardants do little to increase fire safety, and expressed concerns about the link between flame retardants and various health problems, such as developmental problems in children and cancer.

Implementing Rules and Regulations

The law needs the International Sleep Products Association to survey mattress producers every three years to determine what materials are being used to meet flammability standards.

The Bureau of Electronic and Appliance Repair, Home Furnishings, and Thermal Insulation is sanctioned to enforce the new law and adopt implementing rules and regulations.

California is one of a number of states that have banned flame retardants or specific chemicals commonly used in FRs.

San Francisco’s Flame Retardant Ban to Take Effect

• On January 1, 2019, San Francisco’s similar ban on sale of upholstered furniture and juvenile products containing flame retardants goes into effect
• From next year, it will be prohibited to sell upholstered furniture, reupholstered furniture, or juvenile products which have been made with, or contain a flame retardant chemical at a level above 1, 000 parts per million. 
• The same ban goes into effect on July 1, 2019 for similar products that have electrical or electronic components.

Labeling Requirements

• In addition to banning the sale of products with added flame retardants, the San Francisco ordinance includes labeling requirements for all upholstered furniture and children’s products sold in the city. 
• The products must be affixed with labels that state that the item does not contain the flame retardants. 
• The labels required by San Francisco’s ordinance are the same as those currently required under California’s SB 1019, but the label must be marked to indicate that the upholstery materials contain NO added flame retardant chemicals.

Penalties for Violation

Penalties for violation of the ordinance may not exceed $1,000 per day per violation, with each day constituting a separate violation, and each product for sale also constituting a separate violation. In determining the appropriate penalty, the Director or the court will consider “the extent of harm caused by the violation, the nature and persistence of the violation, the frequency of past violations, any action taken to mitigate the violation, and the financial burden to the violator.”

Teknor Apex’s New Medical-grade TPEs Replace Silicone in Biopharmaceutical Tubing

Three new medical-grade thermoplastic elastomers (TPEs) for biopharmaceutical tubing provide performance superior to the industry standard TPE in this application, making them effective alternatives to widely used silicone.
Teknor Apex Company will introduce the new Medalist® compounds at MD&M West (Booth 2015) and will make a presentation on grades for peristaltic pump applications at the “Tech Theater” during the show. The presentation is scheduled for 1:30 pm on Wednesday, February 6.

Clear & Translucent Medalist® Medical TPEs

Teknor Apex recommends three compounds for challenging tubing applications in the biopharma industry for peristaltic pumps and extreme low temperature applications. The materials designed for peristaltic pump tubing provide the elasticity required to keep pace with rapid pump action and the durability needed for the tubing to retain its shape and remain intact over time. In comparison with the industry-standard TPE alternative to silicone, the Medalist TPEs exhibit lower levels of spallation—the shedding of particles from the inner and outer surfaces of the tubing caused by repeated compression and release during pump operation.

Three New Medalist® Compounds

 • Medalist MD-12352 is a 52 Shore A translucent TPE designed for peristaltic pump tubing.
• Medalist MD-50357 is a clear, slightly harder TPE (58 Shore A) for peristaltic pump tubing, which can be sterile welded and heat sealed.
• Medalist MD-10353 is a clear compound used in biopharma tubing in extreme low temperature applications. With a brittleness temperature below -60° C, this TPE can be used for tubing that remains flexible and elastic, facilitating fluid transfer in the manufacturing process of heat-sensitive biopharmaceuticals.
These three Medalist compounds exhibit significantly lower permeability than silicones. They can be sterilized by means of e-beam, gamma irradiation, and ethylene oxide (EtO).
Ross van Royen, senior market manager of regulated products, said: “At a time when silicones are in short supply, Teknor Apex can provide an assured global supply chain for all Medalist TPEs, producing them at ISO-13485-certified facilities in the U.S, and Singapore. As alternatives to silicone, our three new Medalist compounds provide better performance than the industry-standard TPE used thus far.”

Certifications & Compliance

The new Medalist compounds are made with FDA-listed ingredients, are certified at a minimum to the ISO 10993-5 standard for biocompatibility, and are REACH SVHC compliant. They are free of DEHP and other phthalates, BPA, and latex. Standard grades are ADM-free.

Scientists to combine ultrasonic, vibration and heat for flaw detection in aviation

Daria Derusova, JRF from the TPU Research School of High Energy Physics is developing a system combining three methods of non-destructive testing including a vibrational, resonant ultrasonic and thermal ones to test composites for aviation applications.

This approach is of interest for aviation and automobile industries as it will make it possible to monitor the quality of complex and large-sized products made of composite materials taking into account their physical properties. The Russian Science Foundation has supported this two-year project up to 2020.

The project manager Daria Derusova says ‘Every year, new composite materials appear and they challenge existing methods of non-destructive testing. Joints between the materials are of particular complexity and importance.’

Now classic ultrasonic and X-ray testing are used at the production.

The latter is the most accurate but it does not fit to large-sized objects that are presented in aviation a lot. In turn, ultrasonic facilities consume kilowatts of electricity to stimulate materials with a mono-frequency acoustic signal. Laser vibrometry in the combination with resonant stimulation of defects is seen as the most promising modern method. Such an approach allows activating local resonant vibration in the area of damage that also causes the increase of temperature in this area. In turn, an infrared camera will allow the registration of the temperature change and the addition of data about the quality of products. As a result, we expect to build a laboratory facility to test large and complex objects by form. 

Meantime, it will consume several times less electricity than high-power ultrasonic installations. The developed approach will be an alternative to the existing methods of non-destructive testing in aviation and machine-building industry,’ says the early-career researcher.

The facility will comprise of such elements as resonant ultrasonic stimulation using piezoelectric transducers, a scanning laser Doppler vibrometer and an infrared camera with specialized software.
‘The essence of the system is that a tested object – material is exposed to acoustic stimulation in a wide range of frequencies. 

 Elastic waves create vibrations of both material itself and its inhomogeneities. The resonant frequency of vibrations of defects’ walls differs from that of the object that can be detected with a scanning vibrometer. In addition, due to intense resonant vibrations defect areas are locally heated. We register these changes with an infrared camera. The data of quality testing allow us to identify a defect itself, its location, form, and size,’ clarifies Daria Derusova.

In the framework of this project, TPU scientists cooperate with peers from the Institute of Strength Physics and Materials Science SB RAS (Laboratory for Quality Testing of Materials and Structures), the University of L'Aquila (Italy) and the Symbiosis Institute of Technology (India). The S.А. Chaplygin Siberian Research Institute of Aviation (SibNIA, Novosibirsk) provides samples of materials for testing proposed technology.

Saertex wins JEC Asia Award 2018 and AVK Award for use of Saertex Leo materials in Deutsche Bahn’s ICE-3 fleet

The Saertex Leo series stands for optimum fire protection in rail transport, the marine market or the construction industry. For the renovation of the floor panels in 66 trains of the ICE fleet of the Deutsche Bahn with fireproof Saertex Leo materials, Saertex received two awards.

 On November 5th, Saertex was awarded 3rd place at the AVK Award in the Products/Applications category for its project at the International Composites Congress (ICC) in Stuttgart. In addition, the entry won 1st place in the Railways category at the JEC Asia Innovation Award, which was presented on November 15th at the JEC Asia trade fair in Seoul, Korea. 

The Saertex Leo composite system meets the high HL2 fire protection requirements in R10 in accordance with EN 45545 for use in rail vehicles. In contrast to conventional fire protection systems, Leo does not negatively influence mechanical parameters. The Leo system consists of four components, with SAERfoam as the core material, an NFC layer of fiberglass, special Leo infusion resins and a Leo protection layer as the finish.

Saertex Leo thus meets international fire protection standards in the rail vehicle, shipbuilding and construction industries with regard to flame propagation and smoke development. Compared to conventionally manufactured components, the Leo laminates offer impressive mechanical properties and, in the case of the floor panels in the ICE-3 fleet, 50 percent less weight. Train floors are frequently exposed to moisture not only in snowy regions; as opposed to the materials used up to now, the material components contained in the Leo system do not rot.
