Flexible graphite braided packing rings and packing rings are asbestos-free packing rings made of high-quality flexible graphite fibers (or plates) braided (or pressed) after special treatment. This series of sealing fillers have excellent medium corrosion resistance, high and low temperature resistance, good thermal conductivity, fire resistance, wear resistance and self-lubrication performance. Under extreme conditions, they can maintain long-term reliable sealing performance and meet the sealing requirements of ordinary materials which are incompetent. They are rotary and reciprocating transportation of pumps and valves. The ideal asbestos-free sealing filler for power equipment and devices has wide applicability.
