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, odor 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 improves the mechanical properties of higher heat deflection temperature, the chlorine content increases from 56.7% to 63-69%, Vicat softening temperature rises from 72-82 °C to 90-125 °C. And its highest service temperature can reach 110 °C and long-term service temperature 95 °C. Hence, CPVC is a new engineering plastic with promising prospect.
