Definitions for "CPVC"
A modified form of polyvinyl chloride, a synthetic resin that is composed of polymerized vinyl chloride and that, when plasticized or softened with other materials, has some rubber-like properties. A chlorinated polyvinyl chloride has more chlorine atoms per repeating monomer unit than does the polyvinyl chloride molecule. This extra chlorine is responsible for CPVC's strength at high temperatures.
Abbreviation for Chlorinated Polyvinyl Chloride.
