Graphite seal ring are mainly used for mechanical industry. Based on working condition, relevant graphite material can be offered. Resin impregnated carbon graphite, increase the strength and wear resistance, decrease the material porosity. Metal impregnated carbon graphite, increase the density, high temperature resistance.
Resin-impregnated carbon graphite is a new material made of carbon graphite and impregnated resin after high temperature and high pressure. It has high mechanical strength and bearing capacity, low friction coefficient, good self-lubricity and corrosion resistance
Antimony-Impregnated Graphite is a new material made of mixture of graphite and impregnated antimony under high temperature and pressure. It has the advantage of high temperature resistance, low friction coefficient, good self lubrication and excellent corrosion resistance and high thermal conductivity and thermal shock resistance
Easy to machined and can be processed into various geometrical shapes.
