We used to vacuum form Lexan. Two minutes in the oven and pull. Not a
problem.

Lexan must be baked at a low temp. befor raising the temp
enough to bend it. Try 150 to 200 degrees for 12 hrs on a test
piece. The reason is that Lexon has a lot of water in it that
must be driven off at a low temp. That is the same reason
that oil or gasoline make Laxan brittle. They replace the
water. Plexi doesn't have this problem.
