What are the differences between PVC, CPVC and UPVC?

PVC in its original form is brittle and rigid. It is primed for a range of commercial and industrial uses by the addition of additives. Plasticizers make it softer and more flexible. Heat stabilizers increase its resistance to high temperatures. UV stabilizers make it resistant to harsh and lengthy exposure to sunlight.

CPVC is a variant of PVC in which the chlorine content is boosted. It has a higher temperature resistance threshold. It can withstand temperatures of up to 200 F when compared to PVC, which can handle up to 140 F before it melts or fails. For this reason, CPVC is preferred for the transportation of hot water in HVAC systems or industrial settings. CPVC is mandated by building codes for this purpose in many cases.

UPVC is unplasticized PVC or PVC in its original form. Without softening additives, uPVC is brittle and rigid. Although this makes it unsuitable for pipes and other purposes that require flexibility, it has a valuable use in construction. It is resistant to prolonged exposure to sunlight and heat and is used as siding or weatherboarding material on the exterior walls of homes in several countries.
