CPVC is a polymer material modified by chlorination of polyvinyl chloride (PVC) again. After the PVC resin is chlorinated, the chlorine content is increased from 56.7% to 63-69%, which increases the chemical stability and improves the material. The heat resistance, acid, alkali, salt, oxidant and other corrosion. The mixture composed of PVC raw materials and a certain amount of solid additives (without plasticizers) is called rigid polyvinyl chloride (referred to as UPVC).
