SANTOPRENE™ 121-70B260

Technical Datasheet | Supplied by Celanese

SANTOPRENE™ 121-70B260 by Celanese is a medium-hard thermoplastic vulcanizate (TPV) combining a low coefficient of friction with a good bonding to TPV and EPDM rubber. Offers good flowability, excellent processability due to high shear-thinning behavior for injection molding of complex geometries and excellent surface aesthetics providing color harmony with extruded profiles, without surface bleeding nor change of friction after heat aging. It has been designed for complex corner molding and end caps of automotive dense extruded weather seals, either in TPV or in EPDM rubber. SANTOPRENE™ 121-70B260 complies with RoHS.
