ExxonMobil rolls out new TPV challenger to EPDM weatherseals

摘要

US: ExxonMobil has introduced a thermoplastic vulcan-isate (TPV) structure, designed to offer a sustainable alternative to EPDM-based glass-run-channel (GRC) weatherseals. The automotive profile features Santoprene R2, a TPV incorporating post-consumer re-cyclate (PCR), and Santoprene HR TPV, said to match the elastic-recovery of-more difficult to recycle-EPDM. In the "integrated" coextrud-ed structure, Santoprene R2 TPV forms the foot element of the profile, while Santoprene HR is used for the lips and skins of GRC profiles, explained the company statement, issued 19 Jan.
