Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (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 shares most of the features and properties of PVC. It is also readily workable, including machining, welding, and forming. Comparing to PVC, CPVC shares much better performance in the following properties. Heat resistance: CPVC can withstand corrosive water at temperatures
