2 polyvinyl chloride

Polyvinyl chloride (PVC) is a traditional general plastic. Its aging resistance and rubber feel have been greatly improved through modification. However, because of its poor elasticity, it is mainly used as the clamping part of inner and outer side bars and some sealing strips. In trucks and agricultural vehicles, PVC is also often used as a body door frame seal, which is often used as a light colored auxiliary material in a car with EPDM.
