PEI Mercury resistant by 200 bar?

[Albaro]

Hello all,

I want to use polyetherimide (PEI) as electric cable isolation. The isolation is in contact with natural gas. The natural gas contains some mercury. Mercury reacts with copper.
My questions are if PEI is mercury resistant by 150°C and 200 bar or if mercury diffuse into PEI.
I read that PEI is mercury resistant for 150°C by normal pressure. What happen after that temperature and more pressure?
I think its start to diffuse. And diffusing depads of pressure. How does the damage look like?

I hope you can help me or recommed me some literature.
Thanks.
