In 1960, CPVC (Chlorinated Polyvinyl Chloride) was developed as a tough, reliable plumbing material. Today, millions of homes and businesses around the world trust our products to deliver clean, safe drinking water.

About CPVC

Chlorinated Polyvinyl chloride (CPVC) is a specially engineered thermoplastic polymer widely used for the transportation of potable Hot & Cold water in plumbing applications, water in fire sprinklers piping, and chemicals in industrial applications. 

CPVC is a modified version of PVC. PVC is a higher polar polymer that allows working with a wide range of additives that permit a broad range of physical property characteristics. This allows many different compositions of PVC compounds and allows a great diversity of applications from rigid PVC used in pipes to flexible PVC used in packaging etc.

As CPVC is a modified version of PVC, it has a higher level of chlorine than PVC. CPVC becomes an even higher polar polymer, and this polarity permits the use of a wide range of additives that can be incorporated into it. However, due to the higher chlorine content, the use of additives becomes very selective and hence needs more precision.
