CPVC Pipe

CPVC industrial piping systems (SCH80/40 tube, DIN S5/S6.3 tube)

CPVC (chlorinated polyvinyl chloride) was first proposed by the United States BFGOODRICH be in the early 60's commercial production and use of his high temperature and excellent chemical resistance has been used in different industries to get a high rating. CPVC is a PVC on the concept of a single polymer mass formed after chlorination of chlorinated CPVC in different ways because of, condition and amount of chlorine is very different reactions of, CPVC will be the basis of PVC chlorine content increased to 56.7% from the 67 - 74% high. CPVC only limited to the general 63% -67% between the chlorine content only. Chlorine content of CPVC increases will make the hard-brittle transition temperature of polymer Tg significantly improved, in addition to the increase in the basis of PVC molecular weight also makes the same level of chlorine content, Tg also have a certain percentage of increase. CPVC because of its relatively low installation cost, high temperature resistance and excellent chemical resistance, outstanding mechanical strength, non-conductive, the safest and the conductivity of combustion of smoke, making a very important project CPVC plastic material.
