High pressure hydrogen materials (POM, PEEK, Viton, EPDM) compatibility

[Jean-Gabriel Stocker]

Hello Enric,

The Vespel(r) from DuPont(tm), a polyimide (PI) material, can bring solutions for applications in high pressure hydrogen environment.

You can find more details in the brochure at the following link:

I hope it helps,

Jean-Gabriel

As a gasket material, Viton is a very useful material. I think its most important feature is its ability to fully adhere to the surface, even almost to the surface.

I think it can be used as a cell seal, especially at high pressure.

Good morning,

I’ve checked this with the respective product manager and another alternative would be Etrox I, a polyimide material.

There’s a flyer: https://www.roechling.com/fileadmin/downloads/Roechling_Industrial_Brochures_EN_EtroX/Flyer-Industrial-EtroXICM-EN.PDF

and a TDS available here: https://www.roechling.com/industrial/materials/thermoplastics/detail/etrox-i-cm-6121

Hope this helps anyone.

Best regards,
Christiaan

I wanted to post a screenshot of a technical comparison of values of this material and PEEK, PAI, TPI and Vespel, but I can’t upload any image files, sorry. Send me a pm for the technical comparative overview of these materials.

I would be very interested in this comparison as I’m currently looking for the same.

Hello, dear both. We have not yet enabled that feature to upload pictures (because we fear – we might be wrong!) that it will end up in marketing activities. I am nevertheless willing to try it. You can send PM to other members if you first send a connection request (that is accepted). I hope that helps. Kind regards Bjoern

Thanks for your explanation Björn.

I will try sending a PM.

Best regards,
Christiaan
