PTFE packing PTFE braided packing made of pure PTFE fiber, PTFE emulsion and without grease treatment. Because by having a solid braided flexible adjustable, so with the shaft, stuffing box can be a good match with excellent corrosion resistance, good self-lubricating and anti-paste nature. Can be used for chemical, food, *, papermaking, chemical, fine chemical contamination does not allow the operation of the field. PTFE woven (impregnated) packing F4 raw material with the use of warp knit (impregnation) shape, has good chemical stability, self-lubricating properties at high temperatures and humid environments intensity constant, easy loading and removal .

Species [1] can be divided into Kevlar PTFE packing PTFE packing, PTFE packing, Aramid corners PTFE packing, PTFE packing oil, oil PTFE packing , separate wire PTFE packing, PTFE packing oil. First: Aramid PTFE packing with aramid fiber and PTFE as raw material, mixed woven using a special process, high-strength aramid material interwoven in packing inside, making the product more resistant to wear. Is a combination of excellent performance aramid fiber and PTFE fibers make the product more resistant to wear, suitable for higher line speeds and higher dynamic sealing medium pressure. Can be used for chemical, agricultural chemical, petrochemical, pharmaceutical, sugar, paper, power and other industries, reciprocating pumps, mixers, agitators, reactors, valves and other equipment. For water, sewage, oil, grease, weak acid and weak base solution, acid solution, grinding media. Second: White PTFE braided packing made of pure PTFE fiber. Can be used for chemical, food, *, papermaking, chemical, fine chemical contamination does not allow the operation of the occasion, for all chemical media except soluble alkali metal and free fluoride ions. Third: oil PTFE packing is braided by a line containing graphite and PTFE anti-corrosion lubricant made. It has a strong tear strength and high thermal conductivity, low coefficient of friction polishing and it has stability and long life. Can be used for shaft sealing food, *, paper, chemical, fine chemical and other industries, can also be used agitator seal water, steam, solvents and other media, mixers, autoclaves and centrifugal pumps. Apply in addition to strong oxidizing medium vast majority of referrals. Fourth: Oil PTFE packing is braided by a line containing PTFE graphite particles together. Fifth: PTFE packing by a separate wire and sufficiently stretched sintered PTFE woven wire strands, and completely immersed in a PTFE immersed again in the weaving process. Have flexible features, dimensional stability, good resistance to compression, anti-extrusion and high structural strength and density. Is one of the best application results packing industry. Is a universal packing can be used for food, *, paper, chemical and other industries, particularly high-pressure valves, piston pumps, agitators, mixers, high peripheral speed of the shaft, rods, pistons, valves, expansion joints and other equipment. Applies to all chemicals except the soluble alkali metal and free fluoride ions. Long-term use of oil PTFE packing made of pure PTFE braided line and a special lubricant silicone oil, filling boxes with minimum pressure does not change its size: the sixth. Its low coefficient of friction even at high peripheral speed of the heating surface of the shaft can be prevented. For high concentrations of corrosive and oxidizing and chemical products for corrosion medium mechanical seal. Available with the food industry, *, papermaking, chemical, fine chemical contamination are not allowed pumps, valves, flanges equipment.
