CPVC Resin chlorinated polyvinyl chloride for water pipe

Specification:

Improved heat resistance: The softening point temperature is 120°C when the chlorine content is 67%. Therefore,

the heat resistance of CPVC is 20~40℃ higher than that of polyvinyl chloride, and CPVC products do not deform in boiling

water.

Improved mechanical properties: At higher temperatures, some properties of CPVC such as tensile strength, flexural strength

and hardness are improved compared to PVC, with higher rigidity. However, the impact performance of CPVC is worse than that

of PVC and decreases with the increase of chlorine content.

Good corrosion resistance: resistant to acid and alkali at high

temperature, not eroded by hydrochloric acid or hot chlorine steam, resistant to linear alkanes and oils, etc., with excellent

corrosion resistance.

Good flame resistance: It has the characteristics of flame retardant and good air tightness.

At high temperature, it has high insulation resistance and small dielectric loss, and has excellent flame resistance.

Good processing performance: CPVC can be used for the methods commonly used in rigid PVC processing, that is, extrusion,

injection, calendering, turning, milling and drilling can be performed on PVC processing equipment, and the shrinkage rate of the

product Low.

Other properties: Due to the high chlorine content, CPVC does not burn at all and has good flame resistance. CPVC also

has good electrical insulation properties, especially high insulation resistance at high temperatures, low dielectric loss, and

low thermal conductivity, which can be used in the production of various insulating materials. In terms of chemical properties,

CPVC has the same properties as PVC, and can resist acid and alkali at high temperature. CPVC is not attacked by hydrochloric

acid or hot hydrogen vapor, and is also resistant to straight chain hydrocarbons and oils.
