As a new type of pipeline, CPVC pipeline has excellent corrosion resistance. In recent years, it is widely used in steel, metallurgy, petroleum, chemical industry, chemical fertilizer, dye, pharmaceutical, electric power, environmental protection and sewage treatment industries. It is an ideal substitute for metal anticorrosive materials.
Due to the increase of chlorine content in the material, the irregularity of CPVC molecules in the structure increases (the crystallinity decreases, the polarity of the molecular chain increases), so that its thermal deformation temperature rises.
The use temperature of CPVC products can reach up to 93-100℃, which is 30-40℃ higher than PVC. At the same time, it improves the chemical resistance and corrosion resistance of PVC, which can resist the chemical corrosion of strong acid, strong base, salt, fatty acid salt, oxidizing agent and halogen.
