Sisic, features high chemical resistance, high mechanical strength, high thermal conductivity, good friction resistance and self lubricity, is the best among friction materials. The lowest friction coefficient shall be get if it matched with carbon graphite. It can be used to produce all kinds of friction material such as mechanical sealing ring, bearings or axle sleeve, etc. It is widely used in friction resistance parts in high-temperature heat engine, pump valve, petrochemical machine or other industries, such as, automobile, aerospace and ships, etc.
