RTP Company launches new cellulose fiber reinforced PP compounds

Global custom engineered thermoplastics compounder RTP Company has unveiled the latest addition to its Eco Solutions product portfolio with a new line of custom cellulose fiber reinforced polypropylene (PP) compounds.

These compounds, which utilize Weyerhaeuser's Thrive renewable cellulose fiber extracted from trees grown in sustainably managed forests, will facilitate the design and production of environmentally friendly products by providing favorable performance and economics to a wide range of durable applications.

"RTP Company's new cellulose fiber reinforced PP compounds overcome many of the obstacles that have hindered the adoption of bio-based resins and natural fiber compounds," said Will Taber, Business Manager at RTP Company. "They will allow product developers to meet consumer demand for environmentally friendly products that are highly functional yet cost effective. Additionally, they can help processors and OEMs to meet their sustainability objectives by reducing processing costs. On multiple fronts these new compounds provide an unmatched advantage."

Cellulose fibers are a unique reinforcement that can be incorporated into PP to provide increased strength, stiffness, and thermal performance making these compounds suitable for structural applications while providing sought after eco-friendly, renewable content.

In comparison to other natural fibers like wood, hemp, and sisal or natural fillers like wood flour and wheat straw-cellulose fiber provides higher strength and stiffness, consistent color, superior processability, low odor, and a reliable supply.

Advantages cellulose fiber has over glass fiber as reinforcement in PP include: renewable content to meet sustainability objectives, lower energy consumption during processing, specific gravity reductions of 6-9% at like loadings, average cycle time reductions up to 30% for medium to thick walled parts, and reduced tool wear.

Compared to unreinforced PP, a homopolymer PP with 20% cellulose fiber reinforcement offers a 38% increase in tensile strength, a 75% boost in flexural modulus, and a 60°F rise in heat deflection at 66 psi (16°C at 455 kPa). Cellulose fiber reinforced PP compounds from RTP Company also offer strength and stiffness that is comparable to uncoupled glass fiber reinforced PP and achieves approximately 75% of the performance of a chemically coupled glass fiber reinforced PP.

Cellulose fiber can also be combined with glass fiber or impact modified copolymer for materials that meet requirements of more demanding applications. These compounds can also incorporate post-consumer recycled PP to maximize their eco-friendly content. Additionally, they are fully colorable, can be overmolded with select RTP Company thermoplastic elastomers to enhance application ergonomics, and are available worldwide from RTP Company's global network of full-service facilities that provide technical support from design through finished part production.

Cellulose fiber reinforced PP compounds have potential uses in a variety of structural injection molded parts including bezels, bases, brackets, knobs, handles, lids, and housings for the automotive, appliance, furniture, lawn and garden, sporting goods, and toy markets. They are a part of RTP Company's portfolio of Eco Solutions products that provide new design and performance options for manufacturers of eco-conscious products through materials that use bio-based or recycled content resins and natural fiber reinforcement.

Dunlop introduces the new Sportmax Q3 sportbike tire

Dunlop introduces the new Sportmax Q3 sportbike tire

The Sportmax Q3 delivers next-generation sportbike tire performance by incorporating Dunlop’s new Carbon Fiber Technology (CFT).
Dunlop’s new Carbon Fiber Technology (CFT) incorporates a carbon fiber reinforcement element in the Sportmax Q3 tire sidewalls. The many attributes of carbon fiber—high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion—make it a great match for application in the Sportmax Q3.

In addition, the success Dunlop has earned with the Sportmax D211 GP-A in AMA Pro Road Racing has led directly to many of the performance advantages in the Sportmax Q3. There’s the new tread pattern on the Q3, a planned outgrowth of the GP-A tread pattern, featuring fewer grooves that are longer in length to help route water away more effectively in wet conditions. The Sportmax Q3 also features Dunlop’s Intuitive Response Profile (IRP) design for phenomenal steering and handling characteristics, and MT Multi-Tread technology with a tough, cool-running long-wearing compound in the center of the tread plus lateral-grip compounds on the sides. In addition, Dunlop engineers worked to optimize tire carcass construction and tire compounds in the front and rear Sportmax Q3 tires.

Extensive Dunlop testing shows that the Sportmax Q3 exhibits good cornering stability especially at high lean angles, responsive and precise steering characteristics, and predictable and smooth transitional-steering performance for more confidence-inspiring handling.

As the control tire supplier for AMA Pro Road Racing, Dunlop invested in new tire-producing machinery necessary to accommodate race tire production at our Buffalo, New York, manufacturing facility. These same high-tech machines are used to produce the all-new Sportmax Q3, so this serves as another example of how our investments in racing produce results that directly benefit the average street bike owner as well.

Methacrylate adhesives show their strength

The integrity of structural adhesives
Structural adhesives are fast emerging as the preferred alternative to conventional mechanical techniques, such as bolts, rivets and welding, for bonding a wide variety of materials. 

Comprising three main categories, including epoxy, polyurethane and methacrylate, the benefits of structural adhesives are now well documented. Providing a low weight answer to today’s engineering issues, they can be used to bond a variety of substrates, facilitating the strength and integrity of bonded structures whilst lowering stresses, enhancing chemical and temperature resistance, and optimising manufacturing methods.
 
Design trends
There’s no doubt that a variety of composite, plastic and non-plastic materials will continue to play key roles in the drive to create lighter structures across different industries moving forward – from the electronics industry, through to the automotive, aerospace, general transport and oil and gas industries, the list goes on. The consequence of this trend is that various material combinations will need to be bonded together, and structural adhesives are set to play an even greater role in facilitating this.
 
Performance
When you look at how the trend in using various material combinations is evolving, you begin to see why demand for methacrylate adhesives is rapidly increasing. 
Based on thermoset adhesive formulations that provide excellent structural properties, the combination of polymers and impact modifiers have seen methacrylate adhesives emerge more recently to fully compete with polyurethane and epoxy adhesives.
 
Methacrylate adhesives provide a special balance of high tensile, shear and peel strengths with the maximum resistance to shock, stress and impact across a wide temperature range. They can generally be applied without any or little surface preparation when joining similar and dissimilar materials. 
They are extremely versatile in offering good gap filling (up to 8mm) and speed of cure characteristics.  In addition, methacrylates are tolerant to off-ratio mixing, and remain strong and durable under severe environmental conditions.
 
Araldite 2048 and Araldite F348
These methacrylate adhesives exhibit some of the highest lap shear strengths available (24 MPa on aluminium), along with high elongation, making them ideal for dynamic loading. These benefits are offered in combination with good chemical resistance, low ionic content (for electronic applications) and ease of application. They also maintain extremely high impact resistance and elasticity at subfreezing temperatures.  
 
These properties are particularly advantageous for industries such as the oil and gas sector, where these adhesives have been used to assemble offshore polycarbonate pipes onto steel housing, or in the electronics sector, where they have helped both stainless steel and coated substrates withstand impact resistance and vibration. 

They demonstrate that it is possible to achieve bonding between different materials whilst managing structural and weight issues within the design concept.  By being generally faster setting than other adhesives and requiring little or no surface preparation, methacrylates facilitate an even better manufacturing solution.

Sovereign Presents 100% Compostable & Biodegradable GoodLife® Bio Sip-lid Made from Bagasse

Sovereign — one of the leading food packaging suppliers — are proud to introduce The GoodLife® bio sip-lid. Made from bagasse — the fibrous matter that remains after sugarcane or sorghum stalks are crushed to extract their juice — these domed lids are truly innovative, functional and come with impeccable environmental credentials. Unlike other sip-lids which are made of plastic and have a tendency to crack, these lids have a distinctive eco-friendly appearance, are robust and are easy to drink from. After use, the sip-lid is 100% compostable and will biodegrade with general food waste.

GoodLife® Bio Sip-lid Made from Bagasse

The GoodLife® bio sip-lid is firm and comfortable to drink from and can be used safely even with the hottest drinks. Because of the flexible sturdiness of bagasse, the bio sip-lid fits tightly on all 90mm diameter 12oz and 16oz paper hot cups in the UK market. Indeed, tests have shown that the lid stays securely on the cup even if the cup is tipped over.

Speaking about the lid, commercial director Danny Feldman commented "what we love about this lid and what makes it truly stand out from all other sip-lids is that everyone will know it is eco-friendly as soon as they set their eyes on it. There are expensive PLA lids that are compostable available but unless you know what you are looking at it looks just like and can be easily mistaken for any other plastic sip-lid. The GoodLife® bio sip-lid looks, feels and is the most eco-friendly lid on the market today".

The introduction of the GoodLife® bio sip-lid follows several years of research and development and is protected with European Community Design Registration. The GoodLife® bio sip-lid features a visual of their brand icon Eco the Friendly Frog and the word compostable, making it instantly recognizable as an environmentally friendly product.

Price-wise, the bio sip-lid falls approximately midway between the usual market prices for high impact polystyrene and crystallized PLA lids and will therefore be welcomed by the trade as a realistic biodegradable alternative to plastic.

GoodLife® is a registered trademark.
