1, Teflon PTFE anti-corrosion applications
        Because rubber, glass, metal alloys and other materials defects in terms of corrosion resistance, it is difficult to meet the harsh conditions of temperature, pressure and chemical media coexistence environment, the resulting loss is quite amazing. The Teflon PTFE material for its excellent corrosion resistance, corrosion-resistant materials has become a major petroleum, chemical, textile and other industries. Specific applications include: transporting corrosive gas pipes, exhaust pipes, steam pipes, rolling mill high pressure tubing, high voltage aircraft hydraulic systems and cold piping systems, distillation columns, heat exchangers, vessels, towers, tanks lining, valves and other chemical equipment.
        Performance is good or bad seal on the efficiency and performance of the entire equipment has a great impact. Teflon PTFE material with corrosion resistance, aging resistance, low coefficient of friction and is not sticky, wide temperature range and elastic properties make it very suitable for manufacturing high corrosion resistance requirements, the use of sealing temperature higher than 100 ℃ pieces. Such as machinery, heat exchangers, pressure vessels, large diameter vessels, valves, pumps slotted flange seals, glass 11:50, flat flanges, large diameter flange seals, shafts, piston rods, valve stem, Worm pump, rod seals and so on.
 
2, the low friction properties of PTFE PTFE in terms of the load
        Because of the friction device should not be part of any lubrication, such as grease will be dissolved in the solvent and the failure of the occasion or paper, pharmaceutical, food, textile and other industries need to avoid oil contamination of the product, which makes filling PTFE ethylene PTFE material into machinery parts without oil lubrication (directly under load) the best materials. This is because the coefficient of friction of the material is the lowest known solid materials. Specific uses include chemical equipment, paper machinery, agricultural machinery bearings, piston rings used, Machine Tool, guide ring; widely used in civil construction bridges, tunnels, steel roof trusses, large chemical pipelines, storage tanks bearing slider, and as a bridge abutment and bridge swivel so on.

 3, Teflon PTFE used in electrical and electronic aspects
       Teflon PTFE material inherent low loss and low dielectric constant so that it can be made into wire for use in micro-motor, thermocouple, control devices, etc.; PTFE film is manufactured capacitors, radio insulated liner, insulated cables, motors and an ideal transformer insulation materials, aerospace and other industries are also an indispensable component of electronic materials; plastic film with fluorine large oxygen permeability, water vapor and small permselective through this, can manufacture of the oxygen sensor; polar charge with fluorine plastic characteristics Deviations occur at high temperature and pressure, can produce a microphone, speakers, and other components on the robot; using the characteristic of the low refractive index, the optical fiber can be manufactured.
       
4, Teflon PTFE used in medical and pharmaceutical areas
        Polytetrafluoroethylene PTFE pure inert material, has a very strong biocompatible, does not cause rejection of the body, no physiological effects on the human body, can be sterilized by any method, and having up porous structure, which can be used for multi- kind of rehabilitation solutions, including for soft tissue regeneration and artificial blood vessels and patches for vascular, cardiac, general surgery and orthopedic surgical suture.
   
5, the application of Teflon PTFE release properties
       Teflon PTFE material has a solid material with minimal surface tension, does not adhere to any substance, but also has excellent resistance to high temperature characteristics, which makes its application in areas such as manufacturing nonstick release is very extensive. The release process includes two kinds: the polytetrafluoroethylene or PTFE sheet member mounted on the base member, and the PTFE Teflon composite coating or glass cloth heat shrink sleeve and the substrate.
        With the continuous development of materials application technology, the three major disadvantages of Teflon PTFE materials: cold resistance, weldability is difficult, difficult to melt processability is gradually being overcome, so that it is in the optical, electronic, medical, petrochemical output prospect of oil seepage and other areas even brighter.
