Custom PVC sealing strip guide
PVC sealing strip is made of polyvinyl chloride (PVC) as the main raw material, with plasticizers and other ingredients added. They have heat resistance, toughness and ductility, and are mainly used in the door and window, furniture, automobile and curtain wall manufacturing industries. Its production process includes raw material preparation, mixing, extrusion molding and other links. The microwave vulcanization process can improve the surface finish and elasticity. The applicable temperature range is -40℃ to +120℃.
