PTFE includes a popularity of 'king of plastic'
1. The Application of Corrosion Resistance
PTFE material has an excellent property of corrosion resistance, so that it has already been the leading corrosion-resistant materials in petroleum, chemical and textile industry. Meanwhile, since PTFE materials has properties of corrosion-resistance, anti-aging, low friction coefficient and not sticky, wide heat resistance range, good elasticity, it can be used to make the seal which requires a high level of corrosion-resistance and can be used in temperature higher than 1 hundred degrees, for instance, heat exchanger, high pressure vessel, and drawbar seal etcetera.
2. Programs in Construction Industry
The teflon film is the optimal choice for machinery parts, which can lubricate themselves without oil, for the friction coefficient of this material is the lowest in all the known solid components. Its specific applications include used in chemical equipment, paper-making machinery, and it is also vastly used in bridge, tunnel, bridge bearings, bridge swivels or something like them in civil construction engineering.
3. Apps in Electronic and Electric Fields
The inherent properties of low loss and small permittivity enable PTFE resources to be made into lacquered wires, which are parts of micro motor, thermocouple, control devices and the like; PTFE Teflon film is the best insulating material in producing radio-insulated pad, capacitor, insulated cable, motor and transformer. It truly is one of the indispensable industrial electronics in aerospace as well; it may also be made into an optical fiber, for the property of low index of refraction.
4. Apps in the Medical Field
Expanded PTFE material is fully inert and pretty adaptable, so it won't cause rejection or physiological side effects on the body. This materials can be disinfected in any way and has the micro porous structure, subsequently it can be used in various rehabilitation programs, including the using in artificial blood vessel and patch for soft-tissue regeneration, as well as the suture for blood vessel, heart, general surgery and orthopedic surgery.
5. The Application of Anti-sticking Properties
PTFE material has the minimum surface tension among all the solid materials, not adhering to any material, together with the perfect property of heat tolerance it can be now vastly applied in making the anti-sticking layer of non-stick pan or something like that.
With the continuous development of materials application technology, the three major disadvantages of PTFE materials, cold flow properties, welding difficulties and melt processing difficulties, are gradually being tackle, enlarging the prospects of its purposes in numerous areas such as ptfe rod, optics, electronic, medicine, petroleum and chemical industry.
