A Soft, black, versatile thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material combines good physical properties and chemical resistance for use in a wide range of applications. Santoprene rubber is a shear-dependent material that can be processed on conventional thermoplastic equipment for injection molding or extrusion. It is polyolefin based and completely recyclable.
