Chlorinated polyvinyl chloride, or CPVC, offers the process industry superior corrosion resistance, mechanical strength, and excellent life-cycle economics. CPVC provides longer service life, lower maintenance, and improved process utilization compared with many traditional metal materials used in industry.

Conceptually, CPVC is a PVC homopolymer that has been subjected to a chlorination reaction. Typically, chlorine and PVC react according to a basic free radical mechanism.  CPVC and CPVC share similar chemical resistance with the primary difference being temperature handling. PVC has a maximum working temperature of 140°F (60°C) while CPVC has a maximum of 180° (80°C).   Please refer to corrosion resistance table for more details.  Like PVC, installations can use either threaded connections or solvent welded joints.
