Need source for permeability values for Viton

Need source for permeability values for Viton

Need source for permeability values for Viton

(OP)
Hello-
Does anyone know a good source for gas permeability values for viton (a trade name for a fluoroelastomer material)? I can find information for common gases like nitrogen, oxygen, etc. I need it for methyl salicylate, 1-octanol, ethylene glycol, and dimp (diisopropyl methylphosphonate). Does this information exist?
Thanks.

I doubt that the data exists.  You could probably do some rough extrapolations based on molecular size or you could say it is as least as bad as N2.  That would be the worst case I would guess.

DuPont has data for several grades of Viton.
