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

    Posted by Enric Palau on November 2, 2022 at 10:41

    Hello!
    Does anyone have experience with the compatibility of materials with high-pressure hydrogen up to 800 bar?

    For example valve seats in POM (Acetal or Polyacetal). I cannot find any literature that mentions research on this field.

    For valve seats in Peek, it’s wildly used. BUT some literature mentions special reinforced PEEK for hydrogen although I haven’t seen it in the regular PEEK suppliers.

    For gaskets, some literature recommends FKM-AED (Anti-Explosive Decompression) and some other EPDM,

    has anyone experience in those materials compatibility or can point me to some good literature?

    Have a good day!
