PVC or polyvinyl chloride is the most versatile plastic and the use of PVC pipes in buildings is becoming popular day by day. It is possible to substantially change or modify the properties of PVC resin by the technique of compounding, i.e., addition of other additives to PVC. It is, thus, possible to prepare a PVC rigid pipe. PVC is obtained by polymerization of vinyl chloride. Water, kerosene oil, acids and chemicals have no effect on PVC. Hence, it is effectively useful for carrying sewage water and rainwater. PVC pipes are faster to install than other materials. PVC pipes have an expansion coefficient of 0.001°C. PVC sheets of thickness 0.1–12.5 mm can be used as a building construction material. They can also be used as a water proofing material.
