DuPont Engineering Polymers has introduced a new ETPV (engineering thermoplastic vulcanisate) material that the company claims shows better performance than conventional TPEs while offering cost savings to the customer.
DuPont's Fusabond AEB-560D is a new copolymer that will help compounders boost toughness and incorporate glass fibre and other fillers into a wide range of plastics.
Targeted at the modified polymer industry, the new product is a chemically modified ethylene acrylate copolymer that, DuPont claims, provides a more economical functionalised ethylene copolymer for polyamide (PA) modification than standard grafted copolymer technology.
The company adds that AEB-560D resin delivers comparable toughness versus traditional maleic anhydride acrylate terpolymer tougheners. However, it also improves mould flow, produces less reduction in flexural modulus than incumbent intermediate tougheners, provides surface finish advantages, and creates a more cost-effective toughener that maintains its resiliency from room temperature to - 20 degrees C.
It can also be used in other applications to function as a coupling agent, compatibiliser and impact modifier in a wide assortment of resin systems. One of these potential applications is the use as a coupling agent in halogen-free flame retardant thermoplastic wire and cable compositions.
The material is claimed to combine a high performance crosslinked ethylene acrylic elastomer dispersed in a high performance thermoplastic ether ester elastomer. The company sees a number of potential applications for the material in the automotive industry that could result in it being used at a level of 1kg/car.
The American Composites Manufacturers Association participated in a roundtable discussion about the IMAGINE Act. Known as the Innovative Materials in American Growth and Infrastructure, Newly Expanded (IMAGINE) Act, the new bill is designed to promote the increased use of innovative materials like fibre reinforced polymer (FRP) composites, as well as new manufacturing methods to accelerate the deployment and extend the life of infrastructure projects.
After the collapse of a drinking water pipeline in downtown Amsterdam, the Netherlands, Insituform was contracted to reline a close to 100 year old pipe underneath one of the canals. Water was restored successfully within five days, with minimal impact on traffic and the environment.
Australian organisations Austrak, Laing O’Rourke and the University of Southern Queensland (USQ) have joined forces to develop polymer composite solutions for bridge transoms in a $10 million project titled Polymer Composite Transoms for Rail Bridge Deck Replacement (CompTrans).
