CPVC is a new type of engineering plastics with broad application prospects. The resin is a new type of engineering plastics, which is made of chlorinated polyvinyl chloride (PVC) resin. The product is white or light yellow tasteless, odorless, non-toxic loose particles or powder. After chlorination of PVC resin, the irregularity and polarity of molecular bonds increase, which increases the solubility and chemical stability of the resin, thus improving the heat resistance, acid resistance, alkali resistance, salt resistance, oxidant and other corrosion of the material. The mechanical properties of the thermal deformation temperature of the resin are improved. The chlorine content is increased from 56.7% to 63-69%, the Vicat softening temperature is increased from 72-82 ℃ to 90-125 ℃, the maximum service temperature can reach 110 ℃, and the long-term service temperature is 95 ℃. Among them, CORZAN CPVC has better performance indicators.
