Two values are given for each medium, left number = value at 20 °C (68 °F), right number = value at 50 °C (122 °F) Temperature.
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 suit-
ability for use, for example legislation on flammable liquids (explosion protection) is to be taken into particular consideration.
Chemical resistance for other substance on request.
