Two values are specified per medium. Left number = value at 20 °C, right number = value at 50 °C.
Important information
The tables were listed based on specifications from various raw material manufacturers. The values solely refer to laboratory
tests using raw materials. Components made from these are often subject to impacts which cannot be determined in laboratory
testing (temperature, pressure, material strain, impacts of chemical agents, design features, etc.). The values specified can
therefore only serve as a guideline. When in doubt, we recommend performing a test. These specifications do not infer a legal
claim, we exclude any warranty and liability. The chemical and mechanical durability alone do not suffice to determine the us-
age property of a product, particularly e.g. the regulations for liquid fuels (Ex-protection) must be observed.
Durability to other mediums available upon request.
