Kraiburg TPE, Duluth, Ga., launched at NPE2015 new custom high-flow TPEs aimed at automotive applications such as cup holders, air-guide systems, and window seals. They are said to allow for easy cavity filling, resulting in consistent surface gloss. They also boast less off-gassing than competitive grades, which enables the mold to run longer without a halt for cleaning. These grades have very low density—generally 0.93 g/cc—while commonly used PVC has a typical density of 1.40. In a typical rear quarter light window, these TPEs offer a vehicle weight savings of 0.63 lb vs. PVC.
