PVC and CPVC offer the most economical solutions when chemical resistance, self-extinguishing characteristics and good overall physical properties are required at low temperatures. These materials have a high strength-to-weight ratio and good electrical and thermal insulation. PVC is also self-extinguishing per UL flammability tests. PVC may be used to temperatures of 140°F (60°C). CPVC is ideally suited for self-supporting constructions where temperatures up to 200°F (93°C) are present. CPVC also offers excellent flammability properties (meets UL 94 V-0). OCIP stocks PVC in rigid sheet and rod & tube forms, in addition to CPVC, for any project or application.
