A hard black thermoplastic vulcanizate (TPV) combining a low coefficient of friction with a good bonding to TPV and EPDM rubber. The grade offers excellent processability due to high shear thinning behavior for injection molding of complex geometries, with excellent surface aesthetics providing good color harmony with extruded profiles, without surface bleeding nor change of friction after heat aging. Santoprene® 121-80B260 TPV has been designed for complex hard corner molding and end caps of automotive dense extruded weatherseals, either in TPV or in EPDM rubber.Key Features Specially formulated to replace thermoset EPDM rubber in automotive GRC corner molding applications Designed for shorter processing cycle time compared to thermoset EPDM rubber Adheres to vulcanized EPDM rubber and TPV Built-in low COF properties Good flowability with excellent surface aspect
