do a big favor about polyurethane foam
(OP)
hi engineers i am trying to make corbels with pu foam
the problem is that i need more expansion with same hardness at the same time (simultanously) is there any material that i can use it?
second question
i am using silicone mold for pu foam. after 10 to 15 time of use the mols start to tearing that i think its because of reaction heat. is there any solution for this problem and any alternative material for mold?
i hope you understood my talks
and any help is very crucial and appreciated

RE: do a big favor about polyurethane foam
Silicone is known to degrade from chemical attack by epoxy resins. I would surmise that urethanes act similarly. Often FEP film can be used to protect the mold surface from direct contact with resins.
