Polyester is stepping up as a possible resin of choice for European automakers seeking a single interiors material to ease recycling demands.
Polyolefins have been at the forefront of prospects, pushed in part by pending European laws that carmakers take responsibility for recycling more of their vehicles at the end of a car's life.
Other systems are being considered, though, including polyurethane. Now DuPont's engineering polymers group and an unspecified automaker in Germany are studying the prospects for all-polyester instrument panels and door panels.
That study marries a PE substrate with DuPont's Hytrel-brand polyester elastomer in foam versions and as a slush molded skin. The studies are in their early stage, Cole said, with no potential commercial timeline.
