help with plastics(gas diffusion)

[m1cojakle]

Hi everybody.

I am working on something that requires a plastic with high gas permeability but can also retain structural integrity with very thin layers. However, I am not familiar with plastics at all so I have no idea where to start. Any tips would be much appreciated

Are you going to make pipe with it?

It will also help if you define "gas": eg. vinyl is highly permeable to H2S, teflon somewhat pearmeable to HCl,etc.
