Based on substrate type, graphite sheet is primarily categorized into three types: natural graphite, artificial graphite, and composite graphite.

Eserese dị ọcha{{1} dị elu (ọdịnaya ntụ<20 ppm) effectively avoids contamination from metal impurities and is suitable for high-temperature load platforms in semiconductor manufacturing. Isotropic graphite, through isostatic pressing, ensures uniform three-dimensional properties, making it particularly suitable for heat dissipation components in precision molds. For highly corrosive environments (such as hydrofluoric acid and molten alkali), modified graphite sheets impregnated with resin or metal coatings are used, which can improve permeability by 3–5 times.
