What are the properties of graphite composite?

These seals are made of expanded graphite with impregnations and metal reinforcements and offer high resistance to temperatures from -200 °C to 550 °C as well as pressures up to 250 bar. They are particularly resistant to saturated steam, gases, salts, fuels, and numerous chemicals. These properties make them ideal for use under extreme conditions in industrial applications.
