The CPVC resin is made by chlorination modification of PVC resin and is one advanced engineering material. After chlorination, the irregularity of molecular bond of the PVC resin and the polarity of molecular chain increase, the dissolvability and chemical stability of the resin also increase, and accordingly improve the heat resistance and resist the corrosion of acid, caustic, salt and oxidant etc.CPVC is mainly used in pipe, which delivery hot water and corrosion medium.

It can be used to produce the fittings of flow pipe, filtering material, and spin-drier etc, as well as electrical appliances and electronic parts such as wire way, conductor protective layer, electric switch, fuse closure door and insulation material of cable. etc.
