White PTFE Packing with Aramid Corners: The packing is produced by intertexture of white PTFE lines and Aramid fiber, with Aramid fiber getting strengthened in diagonals. The packing can be widely applied in high-pressure working environment. Its structure can not only compensate the lubricating property of Aramid fiber, but also improve the strength of PTFE. White PTFE packing with Aramid corners is designed for reciprocating pump under high-pressure, centrifugal pump with moderate speed and valve. It possesses many advantages including good strength of Aramid fiber, great abrasion resistance of white PTFE and good heat conductivity. It is capable of being applied under the normal working environment to such media as steam, coal, dissolvent, neutral acid, neutral alkali and most easy-to-wear media. It cannot cause pollution in the industries of papermaking, food and sugar refining. White PTFE packing with Aramid corners has much better lubricating property and heat conductivity than others. It is widely used for reciprocating pump, mixer, reactor and valve in the industries of petrochemistry, papermaking, sugar refining and power plant. White PTFE packing with Aramid corners is produce by the intertexture of multi-threads, with Aramid fiber impregnated in the PTFE getting strengthened in diagonals and the seal body being weaved through pure PTFE threads.
