Material Notes:

A soft, black thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material is specially formulated to bond to sulfur or peroxide-cured thermoset EPDM rubber for corner molding, end caps and special fixation applications. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding. It is polyolefin based and completely recyclable.Key Features:Designed for applications requiring excellent adhesion to vulcanized EPDM rubber.Specially formulated to replace thermoset EPDM rubber in automotive glass run channel corner molding applications.Designed for shorter processing time compared to thermoset EPDM rubber.EU and China RoHS compliant.Applications:Automotive- Seals and GasketsUses:Automotive ApplicationsAutomotive Exterior Trim BondingAvailability: Africa & Middle East, Europe, North America, Asia Pacific, Latin America and South AmericaInformation provided by ExxonMobil Chemical
