Chemical Resistance

PVC has high resistance to a wide range of chemical reagents. Such resistance, however, is a function of temperature, concentration and pressure.

In general, PVC has exceptional resistance to attack from high concentrations of alkalis and acids, except for strong oxidising agents at maximum or near maximum concentrations. Information provided is intended as a guide only. Due to the complexity of some chemical reactions, it is suggested that in critical applications, additional long-term testing be performed.

PVC-M should not be used with aromatic and chlorinated hydrocarbons, ketones, esters and ethers.
