Base Material Braiding Selected high-strength para-aramid filaments and carbon fiber yarns are blended and braided. The two fibers are interwoven as one, compensating for the shortcomings of single materials: aramid provides tear resistance and resistance to particle erosion, while carbon fiber is responsible for thermal conductivity, heat dissipation and high-temperature resistance. The braiding density is high and the structure is compact, making it resistant to fiber loosening, shedding, and delamination. Impregnation Treatment The entire is soaked in a graphite PTFE (polytetrafluoroethylene) composite lubricating emulsion, penetrating every fiber. It comes with long-lasting lubrication, reducing the friction coefficient of the shaft, corrosion, and preventing medium penetration. One-piece Molding Process The braided aramid-carbon packing is cut according to the customer's inner diameter, outer diameter, and crosssectional dimensions, then placed in a special mold for high-temperature and high-pressure shaping to form a regular sealing ring with uniform resilience, preventing loosening and deformation. Optional Reinforced Version: Embedded nickel reinforcement, suitable for 400°C ultra-high temperatures, open flames, and coking equipment. III. Eight Core Product Advantages Dual Performance of Wear Resistance Thermal ConductivityPure aramid is only wear-resistant, with poor heat dissipation and a tendency to overheat; pure carbon fiber has good thermal conductivity but is not resistant to particle erosion. The version combines both, doubling the service life in high-temperature working conditions with mud, sand, and slurry. Strong Resistance to Particle Erosion, Difficult to Wear Through Aramid fibers have high tensile strength. In media such as mine slag slurry, pulp, and mortar, sand particles are unlikely to cut or damage the packing, making it suitable for equipment containing solid particles. Stable at High Temperature and High Pressure The conventional version has a long-term operating temperature of -50°C to 350°C, and the nickel-wire reinforced can withstand 400°C for short periods; the pressure resistance can reach 30MPa, making it suitable for steam, hot oil, and high-pressure reaction vessels Graphite-PTFE Self-Lubrication, No Damage to Bushings The dual lubrication layer has low frictional resistance, making it difficult to overheat and seize during high-speed. It will not scratch the pump shaft or valve stem, significantly reducing the replacement cost of bushings. One-piece Molding, Simple and Easy Installation The finished standard ring packing can directly slipped onto the pump shaft or valve stem, with the multi-layer ring gaps placed in an alternating manner. This eliminates the need for on-site cutting, splicing, and wrapping ensuring uniform sealing without material leakage. Resistance to Multiple Chemical Media It is resistant to high-temperature steam, heat transfer oil, sewage, slurry, weak acids and bases oil products, and organic solvents, making it universally applicable in the chemical, thermal power, and mining industries. Durable Resilience, Strong Sealing It is not easily permanently collapsed being pressurized. The packing can be effectively sealed with slight tightening of the gland, reducing the frequency of on-site tightening and maintenance. Asbestos-Free Eco-friendly MaterialIt does not contain carcinogenic asbestos fibers and produces no dust pollution, meeting the environmental acceptance standards of power plants, chemical plants, and paper mills.
