What is the difference between PVC and CPVC?
Chlorinated polyvinyl chloride (CPVC) is created by subjecting PVC resin to a post chlorination reaction that results in additional chlorine atoms on the base molecule. The advantages of doing this is a higher heat distortion temperature and improved fire performance properties. Our CPVC pipe has a maximum service temperature of 200F while the PVC pipe has a maximum service temperature of 140F. CPVC is often used for hot water and other similar service applications where the temperature exceeds the recommended temperature limits of regular PVC.
PVC and CPVC are similar in nature but they are not exactly the same. Chemical resistance, joining and fabricating techniques and service applications must be taken into consideration when choosing which material you will need.
