If you do use this stuff, overate it considerably. It is usually 
recycled and thus has pretty poor electrical qualitites compared to 
virgin LDPE. Despite this, it can be used. Use whatever thickness you 
need, using multiple sheets. With this stuff, I would use about 2mm 
total dielectric thickness for every 10kV AC your tranny puts out.
