Heat Resistance

The temperature at which CPVC softens has been improved by 20 to 40°C compared to general purpose PVC. As a consequence, outstanding toughness and anti-creep properties are maintained even in applications which are constantly exposed to high temperatures, such as hot water pipes and steam pipes, where general purpose PVC would soften, rendering it useless.


By making slight adjustments to the blending and processing conditions for PVC resin, CPVC can be used in various types of molding machines used for general purpose PVC, enabling high-quality products to be obtained.

Chemical Resistance and Corrosion Resistance

CPVC boasts the same chemical resistance as general purpose PVC, and these properties are maintained even at high temperatures.


In contrast to PE, PP and ABS, CPVC is self-extinguishing, generates minimal smoke, and has a high oxygen index, giving it excellent flammability, which makes it optimal as a flame retardant plastic.

Electric Insulation Properties

CPVC's electric insulation properties are superior to other plastics, in the same way as PVC, making it ideal as an electric insulating material.

Treatment/Secondary Processing Properties

In the same way as general purpose PVC, an adhesive can be used to adhere CPVC, making it easy to work with pipes, etc., and welding, bending, sleeve processing and vacuum molding are possible.
