PTFE, shortened type of poly tetra fluoro ethylene is one kind of polymer supplies which is applied extensively in our everyday life, such as packaging, ptfe film, nonstick pan and the like.
PTFE takes the fancy of us mainly owing to its numerous 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, great 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 is 1 sort of solid material which has the lowest surface energy to ensure that solid materials can hardly adhere to its surface. Fifth, function of anti-aging, anti-irradiation, too as a smaller permeability. Its surface and function stay unchanged even after long-ternm of being exposed to extreme atmosphere. Sixth, it's innoxious for its inertia of physiology. Seventh, incombustibility: the limiting oxygen index is below 90. Besides, PTFE has great electrical characteristics; consequently, it can be an perfect insulating material in Level C.
Owing to its exceptional positive factors, PTFE are extensively applied in several field such as chemical industry, petrol, spinning, food, papermaking, medical science, electron, machine etcetera, namely military project of national defense, atomic energy, radio, electric machinery which are the crucial departments in our country. The production made 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 utilised in teflon film and public facilities, like 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 treatment: the expansion of the PTFE materials will not cause organism rejection and physiology side impact due to its robust life adaptability. It is usually applied in disinfection anyhow. Together with its porous microstructure, it is applied on several 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 usually created into enameled wire for its low loss and tiny dielectric coefficient; therefore, it can be applied in micro motor, thermocouple, control device etc.
