Houston, Texas -- ExxonMobil Chemical has commercialised a new Santoprene grade for automotive and construction corner moldings. Used to join EPDM or thermoplastic vulcanisate (TPV) weatherseal profiles, Santoprene says the new grade, TPV B200, "provides excellent adhesion, versatile aesthetics, rubbery touch and critical performance at reduced cost."
The producer said, "Santoprene TPV B200 offers an enhanced bond to EPDM or TPV profiles for more reliable corner seals. Requiring no adhesives or mechanical interlocks, the improved adhesion of this TPV is a result of the unique interaction of the materials during cooling. The bond is designed to last the lifetime of the car over a wide range of temperatures."
â€œThe improved adhesion of Santoprene TPV B200 is critical as traditional corner molding products have not provided the desired bond to EPDM,â€ said Eric Jourdain, automotive weatherseal segment manager, ExxonMobil Chemical specialty elastomers. â€œWe've met that challenge by creating a TPV-to-EPDM bond which performs as well as EPDM-to-EPDM in corner moldings but at significantly reduced costs.â€
