xiros® chemical resistance

The data on chemical or media resistance are based on tests on specimens and on general published data available on the individual components of the iglidur materials. The above information is not applicable to other temperatures and concentrations of the individual chemicals or media. The interactions between the individual chemicals/media are also not taken into account, which may lead to an alteration in the resistance of iglidur® plain bearings. The resistance to these chemicals must be tested under practical operation conditions. All specifications apply to room temperature; significant differences in the chemical resistance can occur at elevated temperatures. This information is based on our present state of knowledge. In principle, we recommend application-specific tests under real application conditions.
