What is the difference between pvc and cpvc?

The ASTM standard allows PVC to be used in applications not exceeding 140 degrees F.Temperatures over this can cause softening of the material and weakening of joints. CPVC on the other hand can handle temperatures up to 200 degrees F. read more

CPVC is also a thermoplastic that is molded into many of the same products as PVC.This difference in makeup allows CPVC to withstand a wider range of temperatures. This is why many building codes require the use of CPVC as opposed to PVC for use in hot water applications. read more

PVC is a thermoplastic polymer, while CPVC is a thermoplastic produced by the chlorination of PVC resin. 2. PVC can be used for a wide number of applications, while CPVC is mostly used for hot and cold water pipes, as well as industrial liquid handling. read more

The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. Above those temperatures, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing. read more
