Silicon carbide is the excellent sealing material. It has light gravity, higher strength, Lower coefficient of friction, anti-radialization,

self-lubricate, easy to be matched with other materials, stable chemical characteristics, heat resistance and good heat spread

etc. According to the different production procedures, there are 2 types of silicon carbide widely used in mechanical seals,

which have different performances.
