CPVC resin is a new type of engineering plastic made by chlorination modification of polyvinyl chloride (PVC) resin.

CPVC resin is a new type of engineering plastic made by chlorination modification of polyvinyl chloride (PVC) resin. This product is a white or light yellow, odorless, non-toxic, loose particle or powder.
After chlorination, the irregularity and polarity of the molecular bonds in PVC resin increase, resulting in increased solubility and chemical stability of the resin, thereby improving its heat resistance, acid resistance, alkali resistance, salt resistance, and corrosion resistance to oxidants. The mechanical properties of the thermal deformation temperature have been improved, with the chlorine content increasing from 56.7% to 63-69% and the Vicat softening temperature increasing from 72-82 ℃ (to 90-125 ℃). The maximum operating temperature can reach 110 ℃, and the long-term operating temperature is 95 ℃. Therefore, CPVC is a new type of engineering plastic with broad application prospects.
