The material is called Glastic GPO-3.

PWD uses sheets of it on their bigger transformers for the HV connections.

What you have there is good for this. Now, you can get that pink colored
insulation board. I can never remember the name of it, but I know Hal Mandel
uses it. It's good stuff that can really withstand HV. Matter of fact, they
make molded standoffs with the stuff. It's used on transformers and in power
centers all the time. If any on here knows the name, please let us know
again, hi hi. Plain epoxy board (without the copper) is good also if you
don't want to etch the traces.

On thing about drilling that board where it wont chip. Use drills pointed
with a sharper angle on the end, and not the shallower ones designed for
steel. The ones they have now with the starter point is excellent. I think
Black & Decker calles their drill line like this "Bullet"? Another thing
that makes it easy to produce a good hole is using a center drill like used
in a lathe. They have a really steep angle of 60 degrees. You don't need a
center punch when using them. If you had one the same OD as the screw
terminal, you could drill the whole thing with it. They do go from about
3/16" up to about 3/4" OD+. Any machine shop supply will have them or maybe
