I am trying to design a small box (25" x 25" x 25") for an uniform heating oven. I am planning to heat around 100 C (212 F) to 130 C (266 F).
I was searching for several material such as green board(<52 C), plywood(<93 C), polycarbonate(<115 C), acry plastic(<71 C) etc. and I found that most of the wood is not recommended to use more than 100 C continuously.
Any recommendation for the material that is cheap and easy to fabricate and also able to use at temperature around 100 C-130 C?
