Is it electrically conductive as well?
Arlo1 wrote:You can get it plain as electricaly conductive and electricaly insulative as well.

Imagine if there were PCBs made with this stuff as core. Then you could make high power electronics with surface mount transistors instead of the big through hole ones. That way you could put more transistor in a small space, to get better current sharing. With a big heatsink on the bottom side of the PCB, cooling of the SMD components would be as good as, or better than, a TO220 on a heatsink.

I imagine that non conductive type just has a tin layer of other non graphite stuff inside or outside. I wonder how heat conductive it is and how many volts it can handle before spark jumps, also how resistant to cuts of sharp transistor edges.
