Klorlu Polivinilklorür reçine (CPVC)

Excellent resistance to aging, corrosion resistance and high flame resistance and so on.

Because CPVC has so superior high temperature, corrosion resistance and flame retardant performance that it has been widely used in making each different industry pipeline, hot and cold pipeline and fire pipeline. The advantages of CPVC pipe can be reflected in the following areas:

1, strong, thermostable
Because CPVC compares PP-R, PE-X to be firm. Compared with PP, the PE-X tube, under the similar pressure, CPVC may use a smaller caliber to achieve the same water flow, thereby saving material costs and installation time. Compares with other thermoplastic, CPVC has the remarkable mechanical property under the different temperature, is suitable for the bearing the situation, the application temperature may reach as high as the life may amount to 50 years.

2, easy installation
The connection method are very similar with PVC. Most commonly used and simple connection method is resolver cementation. Other connection methods are threaded connection, flange connection and electrode connections.
3, non-corrosive oxygen permeability
CPVC have the anti-oxygen, therefore the oxygen seepage from the radiator will not bring metal corrosion.

4, reducing the infiltration of additives
In order to prevent oxidation, some modified plastics needs to increase the massive antioxidant that may be infiltrated into the water supply system, causing the ill-smelling smell.

5, without the impact of chlorine in water
