ExxonMobil Santoprene® 8211-45W237 Thermoplastic Rubber  (discontinued **)

A colorable thermoplastic general purpose non-hygroscopic elastomer, formulated to replace thermoset elastomers such as EPDM, polychloroprene, and chlorosulfonated polyethylene. It can be processed using injection molding, extrusion, blow molding or other melt processing techniques.Key Features: Non-hygroscopic product, requires little to no drying before processing; Neutral, easy coloring formulation; Excellent ozone resistance; Excellent sealing properties; Excellent flex fatigue resistanceAdditional processing comments: This thermoplastic rubber is a shear-dependent material that can be processed on conventional thermoplastic equipment for injection molding, extrusion, or blow molding. For extrusion, a general purpose screw with a compression ratio of 2.5 to 3.0 is recommended. Material can be recycled. SANTOPRENE rubber is incompatible with acetal and PVC.Values below are for injection molded plaques, side gated, 82.6 mm x 117.5 mm x 3.0 mm. Tensile properties measured across flow.
