High temperature resistant carbon fiber gland packing ring is braided by high temperature carbon fiber impregnated with special lubricant and blocking agent through the heart.The packing is firm,flexible and stable in structure, which overcomes the shortcomings of traditional carbon fiber materials,and can effectively prevent the penetration of gas and liquid.high carbon packing has the advantages of stable chemical properties,good lubrication performance,extremely low friction coefficient,high thermal conductivity and protective effect on shaft rod,which is suitable for seals of high temperature and high pressure valves.
