Important note
The tables headed "Chemical resistance of plastics" and "Properties of plastics materials" have been compiled from information from
various producers of raw materials. The figures relate exclusively to laboratory tests on raw materials. Plastics items made from these
materials are often subject to influences which cannot be detected in a laboratory test (temperature, pressure, stresses in the material,
chemical substances, design features, etc.). For these reasons the figures quoted can serve only as a guideline. In case of doubt we
strongly recommend that a test be carried out. No legal claims can be derived from these figures and we disclaim all liability. The
chemical and mechanical resistance of a product does not suffice for the assessment of its suitability for use, for example legislation
on flammable liquids (explosion protection) is to be taken into particular consideration.
Chemical resistance for other substance on request.
