Poly Vinyl Chloride (PVC) is one of the most widely produced and used synthetic polymers. Plasticizers are added during the manufacturing of PVC in order to make it easy to bend and to increase its flexibility.
Well, PVCs are also manufactured without plasticizers in order to make it rigid and sturdy. This material is known as UPVC. SometimesPVC is treated with chlorine using free radical chlorination in order to obtain PVC.
What is UPVC?
Unplasticized Polyvinyl Chloride (UPVC) is the unplasticized PVC in which no plasticizer is included and thus making it rigid. It is also resistant to a wide range of chemical damage. UPVC is a tough, sinewy, transparent and hard-wearing material, and is resistant to the influence of the atmosphere, moisture and various chemicals. It also has excellent electrical properties and low flammability.
UPVC pipes and fittings are widely used all over the world. These pipes are less bendable and rigid in nature. UPVC pipes are especially known for its durability, fire-resistance property and recyclability.

What is CPVC?
Chlorinated Polyvinyl Chloride (CPVC) is manufactured by the chlorination of PVC polymer. Due to the chlorination, it acquires some unique properties like flexibility and the ability to withstand extreme temperatures. It is due to its chlorine content that it has excellent chemical resistance, primarily to acids, alkalis and salts, and is therefore ideal for the chemical process industry.
CPVC pipes are known for their ability to withstand physical and chemical degradation which offers longer life.
Difference between CPVC and UPVC
UPVC does not contain any plasticizers
CPVC is composed of plasticizers
UPVC is not bendable

PVC is a material which is widely used in the production of pipelines. UPVC and CPVC are two types of PVC. The main difference between UPVC and CPVC is that UPVC is made without adding plasticizers whereas CPVC is made by adding plasticizers and undergoing the process of chlorination. However, when it comes to temperature resistance, CPVC can withstand a higher degree of temperature than UPVC.
