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