For the optimal reliability and durability of SERTO products in applications with liquid or gaseous media, it is essential to exercise extreme care when selecting the materials that come into contact with the media. This is especially true for aggressive liquids. The following table on the chemical resistance of elastomers, plastics and metals to numerous gaseous and liquid media is intended to assist SERTO customers in the selection of suitable materials for their applications.
The chemical resistance of materials used by SERTO depends on many factors, such as the temperature of the medium, the degree of contamination of the medium, the admixture of unwanted impurities (e.g. traces of water in gaseous SO2), the concentration of the medium, the simultaneous effect of mechanical forces, e.g. static or dynamic stress, as well as the design characteristics of the product.
In practice, all these factors can influence, for example, the corrosion behaviour, the metallic and chemical resistance of polymer materials. The data contained in the chemical resistance tables cannot, therefore, cover all the working conditions and applications which you will meet in your daily use of SERTO products.
For this reason, the information given in the chemical resistance tables should only be considered recommendations for which we assume no liability. No warranty claims or guarantees can be inferred from this information. The application-specific selection of materials, use, implementation and processing of purchased products lies solely within the scope of responsibility of the customer/user. If there is any doubt, we recommend installing our products - if indicated, in a variety of material combinations - in test installations to be able to determine their behaviour under real operating conditions.
