Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses contain hot and cold water delivery pipes and industrial liquid handling.

Physical properties
CPVC is readily workable, including machining, welding, and forming. Because of its excellent corrosion resistance at elevated temperatures, CPVC is ideally suited for self-supporting constructions where temperatures up to 200 °F (93 °C) are present. The ability to bend, shape, and weld CPVC enables its use in a wide variety of processes and applications.
Heat resistance
CPVC can withstand corrosive water at temperatures greater than PVC, typically greater by 40-50 °C (greater by 72-90 °F), contributing to its popularity as a material for water-piping systems in residential and commercial construction.
Mechanical properties
CPVC is significantly more ductile, allowing greater flexure and crush resistance. The mechanical strength of CPVC makes it a viable candidate to replace many types of metal pipe in conditions where metal's susceptibility to corrosion limits its use.Additionally, CPVC is a thermoplastic and as such has greater insulation than that of copper pipes.
Fire properties
CPVC exhibits fire-retardant properties. It is typically very difficult to ignite, tends to self-extinguish when not in a directly applied flame.
