PVC Plate

PVC (polyvinyl chloride) plate is the workhorse sheet stock of chemical processing. It offers excellent resistance to acids, bases, salts, and a wide range of corrosive solutions at a cost well below most engineering plastics, and it is rigid and dimensionally stable in service. PVC will not rust, corrode, scale, or support bacterial growth, and it is inherently flame retardant with ASTM D635 CC1 and UL 94 V-0 ratings in standard grades. It machines and fabricates easily, bends and thermoforms with heat, and solvent-welds into permanently sealed, chemically resistant joints. That last point is a decisive advantage over polypropylene and HDPE, which cannot be solvent bonded at all.

PVC plate is specified for chemical storage tanks and secondary containment, plating and anodizing line fixtures, scrubber and fume hood components, ductwork and exhaust systems, pump and equipment bases in corrosive environments, machine guards and panels, tank liners and baffles, and signage and display work where chemical exposure or wash-down is a factor. It cuts, routers, drills, and taps cleanly on standard shop equipment and accepts paint and vinyl graphics well. Two limits are worth knowing. PVC softens above roughly 140°F, so hot process fluid or steam service calls for CPVC instead, and standard grades are not UV stable, meaning outdoor installations require painted, capped, or UV-stabilized material. For ambient-temperature corrosive service, PVC is usually the most cost-effective answer available.
