CPVC Plate

CPVC (chlorinated polyvinyl chloride) plate is a rigid sheet stock built for chemical service at temperatures well beyond what standard PVC can handle. The additional chlorination raises the service temperature to roughly 200°F — about 60°F higher than PVC — while preserving the broad resistance to acids, bases, salts, and oxidizers that makes vinyl the workhorse of chemical processing. CPVC is inherently flame retardant, rated ASTM D635 CC1 and UL 94 V-0 in standard grades, and it will not corrode, scale, or support bacterial growth.

CPVC plate is specified for chemical storage tanks and secondary containment, scrubber and fume hood components, ductwork and exhaust systems, plating and anodizing line fixtures, wet-bench and semiconductor equipment panels, pump and equipment bases in corrosive environments, and machined parts and baffles for hot process fluid. It cuts, routers, and drills cleanly with standard shop tooling, thermoforms and bends readily with heat, and solvent-welds with CPVC-specific cement or hot-gas welds for permanent chemically resistant joints — a real advantage over polyolefins, which cannot be solvent bonded at all. Two limits are worth knowing: CPVC is more brittle than PVC, particularly below freezing, so it is a poor choice for impact-loaded or cold-service applications, and it is not UV stable, so outdoor installations require paint or shielding.
