What is the weatherability of Corzan CPVC?
Weatherability is defined as a material’s ability to maintain its basic physical properties after prolonged exposure to sunlight, wind, and rain/humidity. Over 40 years of experience with CPVC, including many long-standing outdoor installations, demonstrate that Corzan™ Industrial Systems will be able to withstand long-term exposure to the environment without significant adverse effects. Corzan CPVC has been blended with a significant concentration of both carbon black and titanium dioxide (TiO2). Both carbon black and TiO2 are widely recognized as excellent ultraviolet blocking agents and help to protect the polymer backbone from the effects of ultraviolet radiation. In fact, Lubrizol experience verifies that the pressure bearing capability of Corzanpiping systems is maintained after extended exposure. Depending on the specific installation, there has been some gradual reduction in impact properties with prolonged exposure. If the specific installation requires additional protection f
