"When thermal graphite is crumpled or bent, its thermal conductivity affects its thermal conductivity." According to the manufacturer, it should not be crushed, bent, or rubbed against a hard surface as it is brittle graphite oriented into fibers. Unfortunately the seller folded the sheet in half, partially breaking it and stuffing it in a small padded envelope, not even paper or cardboard inserts to protect it from folding, so of course it was distorted in transit. I would like to try this product as it sounds. interesting but what I got is clearly worthless due to negligence.
