AES, Trexel will jointly develop auto weatherseal systems

Advanced Elastomer Systems and Trexel Inc. have announced a long-term exclusive agreement to develop dynamic sponge/foam automotive weatherseal systems. Under the agreement, AES will focus on the development of Santoprene thermoplastic vulcanizate products using Trexel’s MuCell microcellular foam process.
According to spokesmen at both companies, the agreement is intended to spur use for innovative dynamic weatherseals that perform comparably to traditional EPDM seals in the areas of compression load deflection, compression set, water absorption and other properties.
"Santoprene TPVs have been used in the transition from EPDM to TPV weatherseals systems for many years, and now we see an innovation potential for overcoming some of the final barriers to broad adoption in dynamic applications," said Zev Gurion, global automotive marketing manager, AES.
Trexel will specify a full turnkey process for Santoprene TPV and will make available standard equipment packages under its worldwide manufacturing and support systems.
