ExxonMobil Santoprene® 121-70B260 Thermoplastic Vulcanizate Elastomer
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Vulcanizate Elastomer (TPV)
Material Notes:	A medium, hard, black thermoplastic vulcanizate (PTV) combining a low coefficient of friction with good bonding on TPV and EPDM rubber. This Santoprene grade offers easy excellent processability due to a high shear thinning behavior for injection molding of complex geometrics and excellent surface aesthetics providing color harmony with extruded profiles, without surface bleeding nor change of friction after heat aging. This product has been designed for complex corner molding and end caps of automotive dense extruded weather seals, either TPV or in EPDM rubber. Availability: Africa & Middle East, Europe, Asia Pacific, Latin America, North America. Applications: Automotive corner molding and end caps, and weather seals. Uses: Outdoor applications. RoHS compliant. Color: Black. Forms: Pellets. Processing Method: Injection molding, multi-injection molding. Information provided by Exxon Mobil.
