Chemical Resistance
Sat.sol Saturated aqueous solution, prepared at 20°C Sol Aqueous solution at a concentration higher than 10 % but not saturated Dil.sol Dilute aqueous solution at a concentration equal to or lower than 10 % Work.sol Aqueous solution having the usual concentration for industrial use Solution concentrations reported in the text are expressed as a percentage by mass. The aqueous solutions of slightly soluble chemicals are considered, as far as chemical action towards polypropylene is concerned, as saturated solutions. In general, common chemical names are used in this document The table serves as a first guideline for users of polypropylene. If a chemical compound is not to be found or if there is an uncertainty regarding the chemical resistance in an application, please contact Technical Department for advice and recommendations on testing.
The table in this document summarizes the data given in a number of polypropylene chemical resistance tables cur- rently in use in various countries, derived from both practical experience and test results.

The table contains an evaluation of the chemical resistance to a number of fluids judged to be either aggressive or not towards polypropylene. This evaluation is based on values obtained by immersion of polypropylene test specimens in the fluid concerned at 20, 60 and 100°C and atmospheric pressure, followed in certain cases by the tensile characteristics. Definitions,symbols and abbreviations The criteria of classifications, definitions, symbols and abbreviations adopted in this document are as follows: S = Satisfactory The chemical resistance of polypropylene exposed to the action of a fluid is classified as “satisfactory” when the test results are acknowledged to be “satisfactory” by the ma- jority of the countries participating in the evaluation. L = Limited The chemical resistance of polypropylene exposed to the action of a fluid is classified as “ limited ” when the test results are acknowledged to be “ limited ” by the majority of the countries participating in the evaluation. Also classified as “limited” is the resistance to the action of chemical fluids for which judgements “ S ” and “ NS ” or “ L ” are pronounced to an equal extent. NS = Not satisfactory The chemical resistance of polypropylene exposed to the action of a fluid is classified as “not satisfactory” when the test results are acknowledged to be “not satisfactory” by the majority of the countries participating in the evaluation. Also classified as “not satisfactory” are materials for which judgement “ L ” and “ NS ” are pronounced to an equal extent.
