In order to simplify the selection of suitable materials when using Bürkert products for aggressive fluids, the following tables provide useful information on the optimal choice of housing and gasket materials for a multitude of media. The table uses a simple coding system where:
+ = material is not affected or is slightly affected by the chemical: suitable
O = various attack level depending on prevailing conditions: limited suitability
– = material exhibits severe attack: unsuitable
The full resistance chart can be found here: Burkert Chemical Resistance Chart
Since corrosion performance is influenced by several factors, the information contained in this brochure should be treated only as a guide and is not necessarily valid for all operating conditions. Increased temperatures, higher concentrations, and the inadvertent ingress of water in originally pure chemicals can all lead to accelerated corrosion.
The information quoted in this guide does not consider the effect of mechanical loading, which may also have a bearing on the material performance in the fluid. In cases of doubt when considering our products, we strongly recommend the prior testing of samples with various material combinations, in order to establish and check their suitability under the actual operating conditions of the application.
Where liquid food products are involved, the plastics and elastomers employed must normally conform with the local food and hygiene regulations. It is emphasized that these resistance tables are intended only as a guide.
