Chemical Resistance

CPVC plate shows an excellent chemical resistance to most acids, alkalines and salts. But when it is used with organic solvents, it swells and physical properties in strength may degrade.
The following table shows the property values of CPVC itself. The property values of its final products can vary largely due to the agents and processing aids.
Please consult with us about the compatibility in the actual application.
