CPVC is light, flexible, tough and provides exceptional corrosion resistance. Because of these and other properties of a high quality engineered thermoplastic, the savings that can be realized in initial installation and continuing maintenance costs are substantial. CPVC handles temperatures up to 210°F. Highly resistant to acids, alkalis, alcohols and many other corrosive materials. Ideal for process piping installation and most service piping applications. Will not rust, scale, pit or corrode, nor are they subject to electrolysis. For buried applications, CPVC is not affected by soil conditions or galvanic corrosion. Painting is not required for indoor non-exposed installations. For outdoor installation where the piping may be exposed to significant sunlight, we recommend painting; two coats of a white or light-colored, water-base, outdoor latex paint provides added protection. Not U.V. stabilized. NSF 61 listed.
