CPVC and PVC pipes are made out of very strong and versatile materials. It is hard to believe that they are not completely resistant to UV rays. Chlorinated Polyvinyl Chloride (CPVC) is made when Polyvinyl Chloride (PVC) is treated with chlorinated water. They are available for engineering and industrial piping projects because CPVC can withstand a greater array of high temperatures.
by olivia. CPVC vs PVC. Most of us are aware of PVC, which is a widely used plumbing material in construction and drainage. It stands for Polyvinyl chloride, and is one thermoplastic polymer that is abundantly used all over the world for plumbing purposes.ssentially, CPVC is nothing but PVC that has been subjected to a process known as chlorination. This chlorination takes place through a chemical reaction called free radical chlorination that makes use of thermal or UV energy.
