Chlorinated Polyvinyl Chloride （CPVC）
Chlorinated polyvinyl chloride is a new-style macromolecule synthetic material and additive, which is made from polyvinyl chlorides colophony of special model and chlorine gas when they have replace-reaction in the condition of solicitation of ultraviolet radiation. It is a kid of white or yellowish fluid powder.
- Properties and specification
Chlorinated Polyvinyl Chloride （CPVC） has characteristics of excellent heat resistance, chemical corrosion resistance, aging resistance and fire resistance property.
