Chlorinated polyvinyl chloride is also known as (poly) perchloroethylene. The polymer compound is obtained by chlorination of polyvinyl chloride. The chlorine content is 61%~68%. It has thermoplastic properties. White powder. Not easy to burn. It is resistant to concentrated acid, concentrated alkali, mineral oil, etc., and the product is not deformed in boiling water. It is more soluble in organic solvents such as esters, ketones and aromatic hydrocarbons than polyvinyl chloride. Used in corrosion resistant paints, adhesives and synthetic fibers.

CPVC has excellent high temperature resistance, corrosion resistance and flame retardancy, and is relatively inexpensive compared to other thermoplastic engineering plastics. Therefore, the use of CPVC is very extensive, and it is widely used in hot and cold water transportation and industrial pipeline water delivery systems for houses, hotels and restaurants; building materials such as cable tubes and profiled doors and windows; decorative materials in aircraft and materials for vehicles and lamps; CPVC sheets are welded into different equipment; in addition, they are widely used in the electronics industry.
