High quality corrosion resistance, and CPVC is resistant to acid, alkali, salt and other organic chemicals and organic solvents, and does not crack in contact with vegetable oil. CPVC has strong corrosion resistance to both acid and alkali, and can be used to transport HCL and NaOH liquids.t has good flame retardancy, low combustion capacity, and can be extinguished immediately after leaving the fire. It will not produce fire droplets, and can inhibit the generation of smoke and toxic gases.The project construction is convenient, the design scheme is more efficient, can directly shorten the construction period, and there is no radioactive carcinogen, which has obvious economic benefits and economic benefits.
