SHC( Carbon Impragnated)

When lubrication condition is limited, better sealing material is demanded. Carbon impregnated sintered silicon carbide products can be an effective solution due to its brilliant low friction coefficient while maintaining the excellent corrosion resistance

With evenly scattered carbon grains of 50-100 micrometer inside, it can avoid sticking of the tracking material effectively and improve the ability to bear dry friction. In the boundary friction, it can lower the friction factor thus less wear and tear.
Widely used in mechanical seals , sliding bearings and others of higher requirements or better dry friction ability.
