Material Notes:
A soft, black, UV resistant thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material combines good physical properties and chemical resistance for use in difficult injection molding 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 fast, easy injection molding, especially for complex part geometries.Used in sealing applications.Recommended for applications requiring superior part surface appearance.Designed to be injected at lower molding temperatures or at lower injection pressures.UL listed: file #QMFZ2.E80017, Plastics - Component; file #QMFZ8.E80017, Plastics Certified For Canada - Component.Although not NSF certified, this product has a Material Supplier Form on file with NSF to facilitate its evaluation for use in applications requiring NSF certification.EU and China RoHS compliant.Applications:Automotive-Glass Encapsulation, HVAC Flapper Door Seals, Seals, Gaskets and Weather SealsUses:Automotive ApplicationsAutomotive Interior TrimAutomotive Exterior TrimAutomotive Under the HoodAvailability: Africa & Middle East, Europe, North America, Asia Pacific, Latin America and South AmericaInformation provided by ExxonMobil Chemical
