Graphite powder is a chemical reaction is very sensitive material, in a different environment resistivity he will change, also is his resistance to change, but one thing is not changed, the graphite powder is one of the very good non-metallic conductive material, as long as the object of the insulation inside guarantee graphite powder uninterrupted, like a thin line, also will be powered, but, how much is the resistance value, this value is not a must but a few, because the thickness of graphite powder, graphite powder used in different materials and the environment resistance will be different.
