CPVC (chlorinated polyvinyl chloride) is a strong, durable thermoplastic produced by the post-chlorination of polyvinyl chloride resin. Originally developed by Lubrizol Advanced Materials, Inc., TempRite® Engineered Materials CPVC can be formed into products that have excellent chemical resistance, can withstand high temperatures and pressure, are weatherproof, and offer high chlorine and biofilm resistance.
Lubrizol offers a wide variety of TempRite Engineered Materials CPVC products, both directly and through our specialty compounding partners.
Material properties vary between resins and compounds within the product portfolio. Please contact us to review your needs and to determine which product would be the best fit.
