PTFE, shortened form of poly tetra fluoro ethylene is one kind of polymer supplies which is applied extensively in our daily life, such as packaging, ptfe film, nonstick pan etcetera.
PTFE takes the fancy of us primarily owing to its various one of a kind positive factors.
First, super insulation: it has a huge volume resistance immune to influence from extreme condition or irregular frequency; Second, outstanding resistance to high and low temperature: hardly can it alter 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's an ideal oil-free material to lubricate which has the lowest friction coefficient in plastics. Forth, non-stick in surface: it is 1 kind of solid material which has the lowest surface energy so that solid supplies can hardly comply with its surface. Fifth, function of anti-aging, anti-irradiation, as well as a smaller permeability. Its surface and function remain unchanged even following long-ternm of getting subjected to extreme atmosphere. Sixth, it is innoxious for its inertia of physiology. Seventh, incombustibility: the limiting oxygen index is below 90. Besides, PTFE has exceptional electrical characteristics; as a result, it can be an perfect insulating material in Level C.
Owing to its distinctive positive factors, PTFE are widely applied in numerous field including chemical business, petrol, spinning, food, papermaking, medical science, electron, machine and the like, namely military project of national defense, atomic power, radio, electric machinery which are the crucial departments in our country. The production produced 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 products manufactured by TACONIC has been utilized in teflon film and public facilities, for example 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 utilized to deliver corrosive gas is made of PTFE, too as the rectifying column, heat exchanger, valve and teflon sheet.
Application in the medicine and medical therapy: the expansion of the PTFE supplies will not trigger organism rejection and physiology side effect on account of its strong life adaptability. It may be applied in disinfection anyhow. Together with its porous microstructure, it can be used on many solutions for recovery covering artificial blood vessel and patch for soft tissue reborn along with the operating suture for vessel, heart, general surgery and plastic surgery.
Application in electronics and electrics: PTFE is often created into enameled wire for its low loss and tiny dielectric coefficient; consequently, it truly is employed in micro motor, thermocouple, control device etc.
