Santoprene® 121-70B265 is a black thermoplastic vulcanizate (TPV) that combines low coefficient of friction with good bonding to TPV and EPDM rubber. This grade offers improved heat aging performance and excellent processability for injection molding of complex geometries with excellent surface aesthetics. It has low friction retention after heat aging without surface bleeding. It has been designed for corner molding and end cap of automotive extruded weather seals in TPV or in EDPM rubber.Key Features Low friction injection molding grade Specially formulated to replace thermoset EPDM rubber in automotive glass run channel (GRC) corner molding applications Designed for shorter processing cycle time compared to thermoset EDPM rubber Adheres to vulcanized EPDM rubber and TPV Built-in low coefficient of friction properties Good flowability with excellent surface aspect
