Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin, which is significantly more flexible and can withstand higher temperatures than standard PVC. Uses include hot and cold water delivery pipes and industrial liquid handling. CPVC is deemed safe for the transport and use of potable water like drinking, cooking & bathing.
Standard :- ASTM F 493
CPVC is readily workable, including machining, welding, & forming. Because of its excellent corrosion resistance at elevated temperature, CPVC is ideally suited for self supporting construction where temperature up to 200 F are present. The ability to bend, shape & weld CPVC ables its use in a wide variety of process & applications.
CPVC is more ductile, allowing greater flexure and crush resistance. Additionally, 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.
Due to its specific composition, bonding CPVC requires a specialized solvent cement different from PVC, with high-strength formulas.Primers, solvent cements, and bonding agents for CPVC report must meet ASTM F493 specifications, differing from PVC solvent cements that must adhere to ASTM D2564 standards.
CPVC is similar to PVC in resistance to fire. It is typically very difficult to ignite and tends to self-extinguish when not in a directly applied flame.
