Graphite materials are porous materials.The porosity of graphite is generally around 15%-20%. In order to improve the bulk density, impermeability, lubricity, strength and other special properties of the product, graphite products still need to be impregnated.

Common impregnating agents are:

1、Coal tar, anthracene oil, coal pitch

2、Artificial resin

3、Metals or alloys

4、Grease

5、Inorganic compoun

6、Other impregnating agents such as PTFE, molybdenum disulfide, sodium silicate, honey, etc.
