Scope of application of PTFE powder

I. Chemical scope

PTFE in any kind of known liquid, neither dissolve nor swell, so PTFE parts in any corrosive media, no matter how long the use, the scale does not change. PTFE manufacturing of large thin-walled containers are widely used in the use of corrosive liquids in laboratories and factories in practice, in addition, it is also widely used in seals, pipe linings, pumps, valves, etc.

       

Second, the scope of machinery

No matter what kind of mechanical equipment, in the work of mutual sliding surface need to smooth to reduce the conflict factor, reduce the wear and heat of the machine parts, to ensure the normal working capacity of mechanical equipment, precision and power consumption. PTFE's low conflict coefficient and self-smoothing, so it is used in the manufacture of bearings, piston rings, machine tool guides and sealing materials, but because of its cost is more expensive, usually used in precision instruments or need acid and alkali resistant environments.

    Three

PTFE has outstanding dielectric properties that are virtually independent of temperature and frequency, and also has high thermal stability, making it an irreplaceable electrical insulator, especially at high frequencies and temperatures and in humid environments. Today many forms of PTFE materials play an important role in the field of electrical and electronic insulation. PTFE glass lacquer cloth and glass cloth for the manufacture of high-temperature and high-frequency insulation materials, used in satellite communications and computers, etc.; PTFE film for the manufacture of capacitors, as an insulation layer between instruments, pads, cables, etc.; PTFE thin-walled tubes of different calibers are used for lead wire sleeves, heat-shrinkable tubes and Spiral tube, generator insulation water pipe, etc.

       Fourth, the construction category

PTFE membrane structure is a new form of construction structure, which integrates construction, structural mechanics, fine chemical and material science - computer technology, etc., with high technical content. By coating PTFE resin on ultra-fine glass fiber fabric, PTFE membrane is light weight, high strength, fireproof and non-combustible, good self-cleaning, unaffected by ultraviolet rays, fatigue resistance, distortion resistance, aging resistance, long service life, high light transmittance, and little heat absorption. It is because of the creation of this intergenerational membrane material that membrane construction has become a modern construction.

       Five, medical field

PTFE is water resistant, physiologically inert and non-stick, and is therefore used in many tissue repair materials and artificial organ materials, such as artificial blood vessels and heart repair membranes. Moreover, the advantage of PTFE is that it can be sterilized by any method, and will not be denatured by high pressure heating or treatment with various disinfectants, so it is widely used in medical devices such as sutures, sterilization pads and injection needles.

At present, all kinds of PTFE products have played a pivotal role in the national economy such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges.
