Got a request for a food grade gasket that will handle ~250 deg. F and
neither degrade nor get soft when exposed to alcohols like methanol and
ethanol at those temperatures (goes between a window that looks into a
reflux condenser on a still and its brass housing). I figured that sheets
of that high temperature plastic that they use for modern spatulas that
you can use in a fry pan and not melt would be a good place to start. But
after some Google work which either gives me way too much or no
information, I'm not finding what kind of plastic it is so I'm tossing it
to you guys. Any suggestions what the material is called and where I'd
find 1/8" - 1/4" sheet stock?

Gore makes some sort of compressible gasket material that works really well
and should have no problem at your temperature. It's a fluorinated material
of some sort I think, similar to Teflon. Not very cheap, though.
