Not epoxy, at least not Araldite. I am dismantling a complicated
electrostatic machine where I used this material for insulation, as
I can draw thick sparks from what should be an insulator...
Polyethylene is a good insulator, but cracks and melts easily.
Acrylic is very good, difficult to beat among easy to find materials.
