Material Notes:
A hard, black, UV resistant 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. 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.Recommended for applications requiring excellent flex fatigue resistance.Excellent ozone resistance.Designed for improved UV resistance.Information provided by Advanced Elastomer Systems
