Abstract

Automotive weather strip should have good weather ability, sealability, durability, etc. to perform its duty as body sealing for vehicles under different harsh environments. Due to its comprehensive properties, thermoplastic vulcanizate(TPV) is widely employed in weather strip as alternative for ethylene propylene diene rubber(EPDM). In this study, the influences of the recycled TPV on the tensile strength and hardness were investigated. As results of the injection molding experiment, the recycled TPV's tensile strength and hardness were higher than the virgin TPV and recycled TPV's extension was improve. The morphology showed that recycled TPV's rubber particles became smaller than virgin TPV's rubber particles.
