Santoprene? 121-40B265
Generic Name: 熱塑性硫化橡膠(TPV) - 提供方: Celanese Corporation
Santoprene? 121-40B265 is a soft, black thermoplastic vulcanizate (TPV) that combines a low coefficient of friction with good bonding to TPV and EPDM rubber, in particular EPDM sponge profiles. This grade offers easy processability due to a high shear thinning behavior for injection molding of complex geometries and excellent surface aesthetics, without surface bleeding after heat or UV aging. This grade has been designed to offer excellent UV resistance performance to fulfill most of the global auto OEMs specifications.This grade has been primarily designed for soft corner molding, sails, muckets and end caps of automotive dense and sponge weatherseals.Key Features High flow injection molding grade Exterior UV stabilized fulfilling SAEJ2527 3.5MJ/m2 and PV3930 5.8MJ/m2 Built-in low coefficient of friction properties Specially formulated to replace thermoset EPDM rubber in automotive weather seal and general molding applications Designed for shorter processing cycle time compared to thermoset EPDM rubber Adheres to vulcanized EPDM rubber (dense and sponge) and TPV Excellent surface aspect
