This comparative index should be considered only as roughly indicative. There are too many variables including chemical type, concentration, temperature and contact time. Even the internal stress level of plastic parts can influence the degree of Chemical Resistance and your choice of material.

Inorganic Acids, bases and salts are used in a variety of concentrations, as mixtures, or on their own. For pure solutions and mixtures the pH value of the solution is a reliable tool when assessing the chemical resistance of semi-crystalline plastics. Specific Chemical Resistance information and charts are available – Refer to Dotmar Technical staff.
