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 pipes and industrial liquid handling. CPVC, as PVC, is deemed safe for the transport and use of potable water, potable meaning water used for drinking, cooking, and bathing.
