I want to find some colored/transparent plastic sheeting that has stable mechanical properties at 100 degrees Celsius, 200 Fahrenheit.
Edit- Sorry i forgot to say the project: It's for an electically insulated prototype drilled and machined box for lithium batteries, with various drill places for the batteries and some places for various screw fixtures. i can't allow the plastic to case to warp at all and i have to foresee a possible scenario where something could be 70 degrees and under tension of springs and so on.
Something very tough, same as plexiglass or pvc sheet.
I wish to have it in a sheet format for example 1/4 inch, 7.5mm
Someone told me that there are some electronics boards and fiberglass epoxies that are stable until 150 degrees C at least...
i dont know anything about plastic, what sheets can i find of that kind? melamine would be ok, except i don't think i'll find melamine sheets round here very easily.
