rubber press pad
(OP)
I'm looking for a rubber press pad/slab in order to apply uniform pressure in a pneumatic wakeboard press where "3d top" surface composite wakeboard are pressed. We press @ 50psi, 70C and 3D relief is about 1/4" deep. What type, thikness and hardness of rubber will work for this purpose? The rubber must be soft enough to fit the 3D surface and hard enough to push out excess resin. Any idea? thanks
