Polytetrafluoroethylene plates, rods, tubes are made of PTFE suspension resin by molding or hydraulic pressing after sintering, or PTFE pre-sintered dispersion resin by the plunger extrusion. PTFE commonly known as plastic king, it has many plastic can not be compared to the excellent characteristics, it can be used for a long time in -180℃ -+250℃ temperatures, has excellent chemical stability, almost resistant to all strong acid and alkali and organic solvent corrosion, it has the smallest coefficient of friction in solid materials, but also has a prominent surface non-viscous, Good electrical insulation and non-aging, non-absorbent, non-combustible and characteristic. So PTFE is indispensable and widely used in various fields of the national economy. It can be processed into a variety of sealing, gasket, electrical insulation electrical equipment parts, can also make a variety of chemical anti-corrosion, high temperature resistance or anti-stick parts or products.
Filled Ptfe products are filled with PTFE resin filler, after mixing, pressing and sintering after secondary processing. This product not only maintains the original characteristics of pure polytetrafluoroethylene but also improves the hardness, creep resistance, abrasion resistance, compression strength, bending strength, thermal conductivity and dimensional stability. General fillers are glass fiber, graphite, copper powder, silica, carbon fiber and so on.
Our production of polytetrafluoroethylene slide using PTFE suspension fine powder resin, cold pressed into billet, sintering forming, pressing grease groove, machined into various specifications of sliding block. With very high compressive strength, low friction coefficient, excellent aging resistance and chemical corrosion resistance, can be used for a long time at -180 to 260℃, good weather resistance. The products are widely used in high-speed rail, bridge and light rail projects, and have been recognized by customers in practical use.
This is the first one.
