Raw Materials

Raw materials. Like all PVC products, PVC pipe gets its properties from combinations of additives and modifiers which are mixed with PVC resin. These include stabilizers and pigments, used selectively to provide color. (For more information on the resin production process, see the general vinyl section.) Once the additives and modifiers have been combined with the resin, the resulting material is called PVC compound, and is in granular form.

Processing/fabricating. In the next stage of manufacturing, these granules are melted down, blended thoroughly and extruded into pipe. Finished pipe is guaranteed strong and safe through third-party certification against criteria of nationally and internationally accepted physical property and general performance standards.
