Hot-pressed graphite is a sintered mixture of high purified ground graphite and resin binder. It has the advantages of excellent corrosion resistance, high cofficient of heat conductivity, self-lubricity, small expansion. It's widely used as blood sperator seals, house-hold pump seal and automotive seal.
