Material The packing features an inner graphite paper core and a flexible pressure graphite packing. It is mainly made from reinforced graphite wires and metal wires, including steel wire, copper wire, nickel wire, carbon fiber, preoxidized wire, glass yarn, and other reinforced graphite wires as raw materials. Key benefits chemical stability and long service life Chemically inert across a pH range of 0 to 14, suitable for a variety of media. speed and temperature capability Designed for services with surface speeds and temperatures beyond what PTFE packing can handle. Low friction and wear resistance Very low friction coefficient supports longterm rust and wear resistance, expanding suitability for bearings and seals. Stable performance in harsh environments Does not react with many chemicals at room temperature and remains stable in challenging chemical settings. Performance and compatibility Material composition supports robust mechanical performance under demanding conditions. Suitable for applications where conventional PTFE packing is inadequate due to speed, temperature, or chemical exposure. Applications and use scenarios Chemical processing equipment Seals and packing in pumps handling corrosive or aggressive media where long service life is required. speed rotating equipment Bearings and seals in systems with elevated surface speeds and temperatures. Industrial valves and static seals Environments with harsh chemicals or demanding duty cycles where chemical stability and low friction are advantageous. Notes The product emphasizes a combination of graphitebased materials and reinforced fibers to deliver chemical inertness, durability, and low friction across challenging service conditions.
