PTFE, shortened form of poly tetra fluoro ethylene is one kind of polymer supplies which is applied extensively in our daily life, which include packaging, ptfe film, nonstick pan etcetera. PTFE takes the fancy of us primarily owing to its quite a few exclusive merits. First, super insulation: it has a huge volume resistance immune to influence from extreme condition or irregular frequency; Second, excellent resistance to high and low temperature: hardly can it change be effected by temperature, and it can withstand an extensive range of temperature from minus 190 degree centigrade to 260 degree centigrade; Third, lubricity: it is an ideal oil-free material to lubricate which has the lowest friction coefficient in plastics. Forth, non-stick in surface: it's one sort of solid material which has the lowest surface energy so that solid materials can hardly comply with its surface. Fifth, function of anti-aging, anti-irradiation, as well as a smaller permeability. Its surface and function stay unchanged even right after long-ternm of becoming exposed to extreme atmosphere. Sixth, it is innoxious for its inertia of physiology. Seventh, incombustibility: the limiting oxygen index is below 90. Besides, PTFE has outstanding electrical characteristics; as a result, it can be an perfect insulating material in Level C. Owing to its special positive factors, PTFE are extensively applied in a lot of field including chemical industry, petrol, spinning, food, papermaking, medical science, electron, machine etc, namely military project of national defense, atomic power, radio, electric machinery that are the essential departments in our country. The production created of PTFE is familiar to us, namely pipe, board. Here lists the main application of the PTFE as follow: Application on Architecture: PTFE architecture membrane material, namely SOLUS series of items manufactured by TACONIC has been utilized in teflon film and public facilities, such as the roof of the stadium, hall of the airport, exhibition centre, station etc. Used for its anti-corrosive property: the pipeline, vent-pipe and steam pipe utilised to deliver corrosive gas is made of PTFE, also as the rectifying column, heat exchanger, valve and teflon sheet. Application in the medicine and medical treatment: the expansion of the PTFE supplies will not cause organism rejection and physiology side effect as a result of its strong life adaptability. It might be applied in disinfection anyhow. Together with its porous microstructure, it really is used on various solutions for recovery covering artificial blood vessel and patch for soft tissue reborn together with the operating suture for vessel, heart, common surgery and plastic surgery. Application in electronics and electrics: PTFE is often made into enameled wire for its low loss and tiny dielectric coefficient; as a result, it truly is utilised in micro motor, thermocouple, control device etc.
