Classification:
1. Classified according to the different crystal form: dense crystalline graphite, flake graphite and cryptic graphite;
2. Classified according to the special molding method: isostatic pressure graphite, molded graphite, extruded graphite;
3. Classified according to graphite particles:detail graphite, medium graphite (particle size about 0.8mm ) and electrode graphite (2~4mm).
Characteristics: high temperature resistance,good conductivity and good thermal conductivity,The lubrication performance depends on the graphite scale. The larger the scale, the smaller the coefficient of friction and the better the lubrication performance;Good chemical stability at normal temperature, acid, alkali resistance and corrosion resistance of organic solvent resistance;Strong plasticity, good thermal shock resistance; soft graphite, black gray; greasy, pollute paper;
