Symbolism for the description of the chemical resistance

+ = resistant (only small changes of the weight, dimensions and properties. According our experiences there is no permanent damage expect).

o = partly resistant (medium changes of the properties. At longer contact time there are permanent damages recommended e.g. degradation of the macro molecular structure).

- = non resistant (strong and permanent degradation in short contact time e.g. stress cracking).

= not tested (no tests were done, no recommendations are possible).

The figures indicated here are approximate values. They may be affected by the temperature, operating time, concentration and stress level of the component involved, by mechanical loads, etc., and the user is not released therefore from the obligation of performing checks and trials of his own. The values indicated here have been compiled on the bases of current experiences and findings. Any legally binding guarantee of certain properties, or any suitability for a specific application cannot be inferred from the present data.
