ExxonMobil Santoprene® 273-50 Thermoplastic Elastomer

Thermoplastic Vulcanizate Elastomer (TPV)

Exxon Chemical

产品说明：

A hard, colorable, specialty thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. It complies with FDA regulations for rubber articles intended for repeated use, as well as those in contact with non-fatty, non-oily foods as closures and sealing gaskets. 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. Recommended for applications requiring excellent ozone resistance.
