CPVC chlorinated method is aqueous suspension (slurry) chlorided. Because chlorinity increase, CPVC molecular not neat increases (crystallinity in the structure to drop, molecular chain's polar enhancement), thus causes its thermal deformation temperature rise. The CPVC product's application temperature may reach ******0°C, compared the PVC enhance ****0°C, simultaneously improved the PVC anti-chemical properties and corrosion resistance ability, can resist the anti-strong acid, the strong alkali, the salt, the fatty acid salt, the oxidant,the halogen and other chemical etching. Moreover, the CPVC tensile strength, the anti-bending strength compares PVC also to have the improvement. Compared with other polymer materials,CPVC has excellent resistance to aging, corrosion resistance and high flame resistance and so on.
Pipes made by CPVC resin and compound have many advantages over PP-R pipe.
Advantages over the PP-R pipe:1)Superior chlorine resistance2)Thinner walls with same pressure bearing capability( less material required)3)Greater UV resistance 4)higher long-term service temperature : *5
