Permeation and Chemical Compatibility of Polymers

Kiwa is your partner for engineering assessments and the corresponding tests. We can determine and prove the suitability of polymers in combination with conventional and unconventional gases and fluids and test under harsh conditions like raised temperature and high pressures.

We can conduct for instance permeation measurements with cryogenic gases on sheets, or permeation measurements of complete piping systems at high pressures (>250 bar) for conventional gases like CH4 and CO2, or renewable gasses like H2, determine the impact of hydrogen sulfide (H2S) exposure on your material over time, or assess the swelling of your liner material due to hydrocarbons or other chemicals.

You can find more specific information in this leaflet.
