PTFE, shortened form of poly tetra fluoro ethylene is one kind of polymer materials which is applied extensively in our day-to-day life, like packaging,
ptfe film, nonstick pan and the like.
PTFE takes the fancy of us mainly due to its numerous exceptional advantages.
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 perfect oil-free material to lubricate which has the lowest friction coefficient
in plastics. Forth, non-stick in surface: it's 1 kind of solid material which has the lowest surface power to ensure that solid materials can hardly
abide by its surface. 5th, function of anti-aging, anti-irradiation, too as a smaller permeability. Its surface and function remain unchanged even soon
after long-ternm of being subjected to extreme atmosphere. Sixth, it is innoxious for its inertia of physiology. Seventh, incombustibility: the limiting
oxygen index is below the age of 90. Besides, PTFE has exceptional electrical characteristics; for that reason, it truly is an perfect insulating
material in Level C.
Owing to its special advantages, PTFE are extensively applied in several field which includes chemical industry, petrol, spinning, food, papermaking,
medical science, electron, machine etc, namely military project of national defense, atomic energy, radio, electric machinery that are the vital
departments in our nation. The production produced of PTFE is familiar to us, namely pipe, board.
Here lists the leading 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, including the roof of the stadium, hall of the airport, exhibition centre, station and so on.
Used for its anti-corrosive property: the pipeline, vent-pipe and steam pipe utilised to deliver corrosive gas is created of PTFE, at the same time as
the rectifying column, heat exchanger, valve and teflon sheet.
Application inside the medicine and medical therapy: the expansion of the PTFE materials will not trigger organism rejection and physiology side effect
because of its powerful life adaptability. It could be applied in disinfection anyhow. Together with its porous microstructure, it really is applied on
numerous solutions for recovery covering artificial blood vessel and patch for soft tissue reborn together with the operating suture for vessel, heart,
general surgery and plastic surgery.
Application in electronics and electrics: PTFE is usually produced into enameled wire for its low loss and tiny dielectric coefficient; hence, it truly
is utilized in micro motor, thermocouple, control device etc.
