Composition: PTFE yarns, silicone rubber core, braided
Application:
It is most useful in slower shaft speed applications. The rubber core provides a low friction finish and
prevents leakage through the braid. Chemical, paper, dye and fertilizer industries. Steam, fuels, water,
dilute acids and alkalies, organic compounds, oils, greases and solvents, etc.
Equipment:
High elastic red silicone rubber core can absorb vibration, to control leakage, suitable for worn-out
pumps.Centrifugal pump, mixer, agitator, stern tube. Etc.
Size:3×3mm--50×50mm;Others can be produced according to client's requirement

The packing is also called a sealing packing, which is usually woven from a softer thread, and is filled in a sealed cavity by a strip having a square cross-sectional area, thereby achieving sealing.
Today, the packing is mainly made of graphite and various fibers. According to different requirements, carbon fiber, copper wire, 304, 316L, Yinzhi nickel alloy wire and other materials are used.
1)Aramid series
Gold aramid fiber packing, yellow aramid fiber packing, aramid fiber interlaced with white PTFE packing, aramid fiber interwoven black PTFE packing. This series of packing is made of aramid fiber as the main material, multiple times impregnating lubricant, tetrafluoro-emulsion Such as precision preparation. It has good high resilience, chemical resistance, low cold flow and high line speed. Compared with other types of packing, it can resist particle crystallization medium and higher temperature. It can be used alone or in combination with other packings. It is mainly used in the case of many media particles and easy to wear.
2)PTFE series
White PTFE packing, black PTFE packing, white PTFE interlaced aramid fiber packing, black PTFE interwoven aramid fiber packing, PTFE pre-oxidized wire packing, white PTFE immersed silicone oil packing, white four Fluoride-impregnated rubber packing This series of packing is made of polytetrafluoroethylene as the main material. Excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stickiness and good resistance to aging. It can work for a long time at a temperature of +250 ° C to -180 ° C. In addition to molten metal sodium and liquid fluorine, it can withstand all other chemicals and does not change when boiling in aqua regia. It is mainly used under the conditions of high sanitary grade, high corrosiveness, high linear velocity and easy wear under the working conditions that do not allow pollution.
3)Graphite series
Flexible graphite packing, metal reinforced graphite packing, carbon fiber reinforced graphite packing, carbon fiber metal reinforced graphite packing This series of packing characteristics is made of graphite as the main material. It has good self-lubricating and thermal conductivity, small friction coefficient, strong versatility, good flexibility, high strength and protection for the shaft. According to different requirements, it can be reinforced with carbon fiber, copper wire, 304, 316L, Yinzhi nickel alloy wire. Mainly used under high temperature and high pressure conditions.
4)Carbon fiber series
Carbon fiber reinforced graphite packing, carbon fiber metal reinforced graphite packing This series of packing is mainly made of carbon fiber. Carbon fiber is a new material with excellent mechanical properties. Carbon fiber has no creep, good fatigue resistance, small thermal expansion coefficient and corrosion resistance. Good sex and good thermal conductivity. Mainly used under high temperature and high pressure wear conditions.
