Highlighting The Difference Between CPVC and UPVC Pipes

difference between CPVC and UPVC pipes

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?

Unplasticised Polyvinyl Chloride, commonly referred to as UPVC other than its full form, is rigid PVC, lacking any plasticiser. Renowned for its resilience, UPVC stands as a tough, sinewy, transparent, and durable material, exhibiting resistance to atmospheric influences, moisture, and various chemicals. It boasts excellent electrical properties and low flammability. Globally, UPVC pipes and fittings are widely embraced, known for their inherent rigidity and resistance. UPVC pipes, recognised for their durability, fire-resistance, and recyclability, epitomize a reliable choice in diverse applications worldwide.

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.

Application of UPVC Pipes

Final Note

PVC, a widely utilised material in pipeline production, comes in two distinct types: UPVC and CPVC. The critical difference lies in their composition, UPVC is made without plasticisers, while CPVC involves the addition of plasticisers and a chlorination process. When evaluating temperature resistance, CPVC surpasses UPVC in its ability to withstand higher temperatures.
