Resistance list

With the use of aggressive products, the user is very often confronted with the product compatibility of devices. 
The following resistance list is based on various material charts and is supplemented by our own trials and experiences. 
These specifications are not always applicable to the real operating conditions because corrosion is affected by different factors. Corrosion is influenced by temperature, increase in concentration, high flow rate and mechanical loading.
Deviations are possible especially in case of elastomer seals which are due to the different manufacturing processes of the manufacturers (it cannot be identified from the trade mark e.g. Viton).

We cannot give any specifications for the diffusion behaviour of plastic materials and elastomer seals.

The resistance values mentioned here are approximate values only and are just for information purposes. These values should help the user to find the appropriate instrument type but are not a guarantee.

The resistance values relate to a temperature of 20° C and to a concentration of 100% unless otherwise specified.
