Material - Flexible high-pressure graphite packing with an inner graphite paper core - Main raw materials include reinforced graphite wires and metal wires (steel, copper, nickel), carbon fiber, pre-oxidized wire, glass yarn, and other reinforced graphite components Key benefits - High chemical stability and long service life - Chemically inert across the full pH range of 0 to 14 - Designed for services with surface speeds and temperatures higher than those supported by PTFE packing - Extremely low friction coefficient, contributing to long-term wear and rust resistance - Does not react with many chemicals at room temperature and remains stable in harsh chemical environments Performance and compatibility - Material and construction provide reliable performance in demanding sealing and bearing applications - Suitable for use in environments where chemical resistance and low friction are critical - Maintains stability under aggressive or variable chemical conditions and temperatures beyond standard packing materials Applications and use scenarios - Sealing and bearing components in high-speed pumps and valves in chemical processing and related industries - Rotating equipment requiring low friction and long-term wear resistance, such as bearings and seals - Seals for systems handling corrosive fluids or harsh chemicals across a wide pH range (0-14), where PTFE packing is inadequate Notes - The design emphasizes compatibility with high surface speeds and elevated temperatures - Material composition supports long service life in aggressive environments without compromising chemical inertness or mechanical performance
