Silicone (PDMS) Membrane Chemical Compatibility Chart

This is an initial guide for screening the suitability of silicone for contact with certain substances. In addition, other factors such as temperature, pressure, concentration, and length of exposure can play a significant role in determining the suitability of silicone membranes in your intended application.

It is the responsibility of the user to determine the suitability of silicone membrane modules in its specific application and to be satisfied with its own testing that the membrane module is fit and suitable for use with its intended application and that such application is a safe application.

TYM does not warrant (either expressed or implied) that the information in this chart is accurate or complete or that TYM membrane modules are suitable for any purpose.
