What Are the 4 Types of PVC?

2023-08-15

There are 4 main types of PVC:

Unplasticized PVC (PVC-U): This is the most common type of PVC. It is strong, durable, and resistant to chemicals. PVC-U is used for a variety of applications, including pipes, windows, and siding.

Chlorinated PVC (CPVC):CPVC is similar to PVC-U, but it is more resistant to heat. This makes it a good choice for applications where hot water is used, such as hot water pipes and radiant heating systems.

Molecular Oriented PVC (PVC-O): PVC-O is stronger and more flexible than PVC-U and CPVC. This makes it a good choice for applications where high strength and flexibility are needed, such as underground pipes and window frames.

High Impact PVC (PVC-Hi):PVC-Hi is more impact-resistant than PVC-U and CPVC. This makes it a good choice for applications where there is a risk of impact damage, such as playground equipment and traffic cones.

In addition to these four main types, there are also a number of modified PVCs that have been developed for specific applications. For example, there are PVCs that are flame-retardant, UV-resistant, and chemically resistant.

The type of PVC that is best suited for a particular application will depend on the specific requirements of that application. For example, if you need a pipe that is strong, durable, and resistant to chemicals, then PVC-U is a good choice. If you need a pipe that is resistant to heat, then CPVC is a better choice. And if you need a pipe that is strong, flexible, and impact-resistant, then PVC-O is a good choice.
