Durable in Harsh Conditions

Whether commercial or industrial, selecting or upgrading materials for a piping system, ducting, tank lining or another large application is a major investment. These costs can multiply if the material chosen can’t stand up to harsh conditions.

The Corzan® CPVC compound is produced with tight quality control and testing to produce consistent results under the harshest conditions, especially in outdoor installations. Products made with Corzan CPVC have proven durable against ultraviolet light, temperature extremes, impacts and burial and harsh chemicals.

Ultraviolet Light

Corzan CPVC is suitable for outdoor installations due in part to its resilience against ultraviolet (UV) light compared to other plastics. PEX, for example, is quite vulnerable to UV light: UV light catalyzes the oxidation process of the chlorine-inhibiting antioxidants in PEX piping. Imagine a rooftop HVAC system made with PEX: stripped of its antioxidants by sunshine, PEX becomes vulnerable to attack from chlorine. This weakens the pipe, and the possibility of failure greatly increases over time.

Corzan CPVC is blended with an ideal concentration of both carbon black and titanium dioxide (TiO2) that has been tested to produce the best performing compound with the benefits of UV resistance. When exposed to sunshine or other UV light, Corzan CPVC’s grey color may change slightly, but UV light does not weaken Corzan CPVC. In fact, only a very small amount—a fraction of a millimeter—of the pipe’s surface experiences discoloration. A cross section of a pipe would reveal only the very top layer is discolored. Pressure-bearing components remain strong even after significant UV exposure and only degrade with age – as does any material. And Corzan CPVC can be painted with water-based acrylic latex paint to further protect it from UV exposure.
