Any plastic guru's here?

Looking to replace a peice of 3/4" plywood with some type of plastic.
Application is in a heated press used to join rubber sheets. *Problem
with the plywood is it compresses in use, and as it gets thinner the
bolts used to hold the whole thing together start to stick out and the
unit requires frequent retorquing.

Need some type of plastic that does not compress like wood, can
withstand 350 deg F for 1 hour, and idealy would have a coeffient of
expansion close to aluminum.

Gargolite G7 looked nice until I saw the price of a 2 x 3 foot peice
at $1140.00. I would need 2 x 4 or 5 foot peices.

Any suggestions.

Thank You,
Randy
