Impregnation graphite material is a composite material that fills impregnating agents such as resin and metal into the pores of graphite through an impregnation process and then solidifies through heat treatment. By combining graphite with matrix materials such as resin, copper, antimony, etc., the conductivity, wear resistance or corrosion resistance of the matrix material can be improved.

Main types of Impregnated graphite material are: Resin impregnated graphite, Copper impregnated graphite material, antimony impregnated graphite, silver impregnated graphite and others.

See some Typical types of impregnated graphite materials below:

Pure graphite material will volatile due to volatile substances in the adhesive and binder aggregation, decomposition and carbide, when baking, thus appeared the pore (10% ~ 30% porosity). If pure graphite Used as sealing ring, it will be permeable or leakage, and strength is low, so we fill the gap increased, and make it not permeability after resin process, it also increased the strength. But the heat resistance and corrosion resistance have varying degrees of decline. Impregnated material use mainly 3 types of material: organic resin, inorganic substances and metal.

Resin impregnated graphite: high density (up to 2.0-2.5g/cm³), but poor high temperature resistance (about 200℃ or less), suitable for corrosive environments;

resin impregnated graphite material is a composite material that is impregnated with synthetic resin into the surface and internal pores of graphite and then solidified through heat treatment. Its core feature is to improve the mechanical strength and corrosion resistance of graphite through the impregnation process while retaining its excellent thermal conductivity. main grade names that we produce: M106H， M120H， M106K，M120K， M254K

Metal impregnated graphite: Combines the high temperature resistance of graphite (up to 800°C or more) and the mechanical strength of metal to improve wear resistance and conductivity.

Copper impregnated graphite material uses carbon graphite as the base material and impregnates copper alloy through vacuum pressure. Utilize the high hardness, good lubricity and chemical stability of carbon graphite as the base. Utilize the high melting point, ductility, high thermal conductivity and corrosion resistance of copper alloy to form a continuous, stable and high mechanical strength mechanical sealing material. Current products have been widely used in metallurgical continuous casting machine, rolling just equipment, mining machinery, shipping, steam turbine, water turbine, injection molding machine and equipment in the production line. main grade name that we produce: M106P，M120P， M254P
