PVC is sometimes known as ‘Vinyl’ in Europe In Europe, ‘Vinyl’ usually refers to certain specific flexible applications, such as flooring, decorative sheets and artificial leather.
The basic raw materials for PVC are derived from salt and oil.
Chlorine is manufactured by the electrolysis of sodium chloride, salt.
This is why the first PVC manufacturing plants were located close to natural sources of salt.
PVC pipe is manufactured by extrusion in a variety of sizes and dimensions and generally sold in 10' and 20' lengths. PVC pipe is available in both solid wall or cellular core construction. Cellular core construction involves the simultaneous extrusion of at least three layers of material into the pipe wall: a solid outer layer, a cellular core intermediate layer, and a solid inner layer. PVC pipe is made to conform to various ASTM standards for both pressure and non-pressure applications.
