Material Notes:

A hard, colorable, flame retardant thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material has good fluid resistance and contains non-ether brominated flame retardants (non-furan emitting). It does not contain added antioxidants or metal deactivators. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding, extrusion or blow molding. It is polyolefin based and completely recyclable.Key Features: UL listed: file #QMFZ2.E80017, Plastics - Component; file #QMFZ8.E80017, Plastics Certified For Canada - Component.Recommended for applications requiring excellent flex fatigue resistance.Recommended for applications requiring excellent ozone resistance.EU and China RoHS compliant.Applications: Automotive – Flame Retardant Connectors and SealsElectrical – Flame Retardant Connectors and seals; Flame Retardant Wire and Cable JacketUses: Automotive ApplicationsCable JacketingFlexible Cord JacketingWire & Cable Applications Availability: Africa & Middle East, Europe, North America, Asia Pacific, Latin America and South AmericaInformation provided by ExxonMobil Chemical
