CPVC is a new type of engineering plastic, produced by chlorination of polyvinyl chloride(PVC) resin. CPVC is white or light-yellow granules or powder without any smell, ordor or toxicity. 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. Therefore, the heat resistance and the corrosion resistance of acid, caustic, salt and oxidant improve. It also improve the mechanical properties of higher heat deflection temperature, the chloride content increases from 56.7% to 63-69%, Vicat sofening temperature rises from 72-82ºC to 90-125ºC. And its highest service temperature can reach 110ºC and long-term service temperature 95ºC. Hence, CPVC is a new engineering plastic with promising prospect.
