Difference between cpvc and upvc

uPVC and cPVC are two popular options for piping systems. Although they are similar in appearance, composition, and application, they do have a difference.

uPVC (Unplasticized Polyvinyl Chloride) is a type of PVC material that is rigid and strong, making it a popular choice for piping systems. uPVC is resistant to chemical corrosion, making it a great option for systems that will carry chemicals or liquids that could corrode other piping materials. Additionally, uPVC is safe for drinking water and can withstand high temperatures.

On the other hand, cPVC (Chlorinated Polyvinyl Chloride) is a type of PVC material that has been treated with chlorine. cPVC is a stronger and more durable version of PVC, thanks to the chlorine treatment. This makes it a popular option for high-pressure systems, especially systems that carry hot water. cPVC is also resistant to chemical corrosion and safe for drinking water.

Some of the key differences between uPVC and cPVC include:

1. Composition - uPVC is made from PVC resin and other materials such as stabilizers, whereas cPVC is made by chlorinating PVC resin.

2. Working Temperatures - While uPVC can withstand temperatures of up to around 85°C, cPVC can handle temperatures of up to 95°C. This property makes cPVC a popular choice for hot water systems.

3. Chemical Resistance - Both uPVC and cPVC are resistant to chemical corrosion. However, cPVC is more resistant to chemicals than uPVC.

4. Cost - cPVC is generally more expensive than uPVC, due to its additional processing.

5. Installation - Both uPVC and cPVC are easy to install and can be cut with a saw or a cutter. However, cPVC requires special glue for joints, while uPVC can be welded together.

6. Applications - While both uPVC and cPVC are used in a variety of applications, cPVC piping is commonly used in hot water systems, where uPVC is best suited for drinking water systems.

In conclusion, both uPVC and cPVC are excellent choices for piping systems. However, which one you choose depends on your specific needs and requirements. If you need a piping system that can handle high temperatures or harsh chemicals, cPVC is a better choice, but if you need a piping system for drinking water or general plumbing, uPVC is the way to go. Ultimately, whichever option you choose, make sure to work with a reputable manufacturer or supplier to ensure that you get a quality product that meets your needs.
