Before you could understand the difference between CPVC and UPVC know UPVC and CPVC full form. UPVC is Unplasticized Polyvinyl Chloride while CPVC is Chlorinated Polyvinyl Chloride.
CPVC is produced by chlorinating the PVC polymer. CPVC has 67% chlorine. Hence it is suitable for both hot & cold water application. Chlorination makes the CPVC material more strong/rigid, chemical resistant and gives them the ability to withstand high temperatures up to 93deg C.
CPVC pipes are bendable and exhibit fire-retardant properties, which means they can slow down or stop the spread of fire and are used in fire sprinkler systems. Apart from being resistant to chemicals, CPVC is resistant to many acids, alcohols, hydrocarbons, bases, etc.
On the other hand, UPVC and PVC are both the same. UPVC has 57% chlorine hence it is suitable for only below 60deg. C application or cold water application. UPVC pipes are long-lasting, recyclable, and are fire-resistant also.
Difference Between CPVC & UPVC or PVC
The primary difference between CPVC and UPVC lies in its resistance to temperatures. While CPVC can withstand upto 93 Deg C temperature which makes it suitable for both hot and cold water, UPVC can withstand only upto 60 Deg C and as such is suitable for cold water applications only.
