Five application areas that PTFE is used

2020-06-11

Teflon chemical formula is: -[-cf2 =CF2-]n- and teflon is a polymer material. PTFE involves a wide range of industries, such as machinery, aerospace, products, food.

PTFE is often made into ptFE gaskets due to its strong corrosion resistance and good sealing performance. At present, ptFE gaskets are widely used in military, machinery, flange and other fields. In addition, ptFE has strong corrosion resistance, outstanding insulation performance and other characteristics. so PTFE pipelines are used in petrochemical and other industries to transport corrosive gas. Teflon bar materials also has good chemical stability, low friction coefficient, non-adhesion and other excellent characteristics, used as the corrosive medium liner sealing, lubrication materials and insulation parts.




01

Anti-corrosion materials

Polytetrafluoroethylene (PTFE) has overcome the shortcomings of common plastics, metals and other materials which are not corrosion resistant. Thus, PTFE has become the main corrosion-resistant materials in petroleum, chemical industry and textile industry. For example, it is used to make pipes, exhaust pipes, steam pipes, etc. that carry corrosive gases.




02

Oil-free lubricating material

Teflon is the lowest friction coefficient in engineering plastics. So it is the most ideal material for oil-free lubrication of mechanical equipment parts. In the food industry, paper industry, textile industry and other areas where lubricating oil will make the product contaminated, teflon is a good solution to this problem.




03

Advanced dielectric material for electronic equipment

PTFE in recent years has been listed as the ideal cable wire insulation materials, polytetrafluoroethylene is its low loss, friction resistance, anti-aging, dielectric constant, thermal stability and certain flexibility, such as PTFE porous design can be made to minimize the loss and distortion rate, it is a good medium filling material, is widely used in computers, telecommunications, aerospace, defense, and many other challenging field.




04

The adhering materials

PTFE is resistant to high and low temperature and it does not adhere to any material. Besides,  its surface tension is minimal, non-toxic , which made it mainly used in microwave ovens and non-stick pot liner.




05

Medical material

Tetrafluoroethylene itself is non-toxic, so its excellent mechanical properties, durability, biological adaptability will not cause body reaction. So it is widely used in medical treatment. Polytetrafluoroethylene products in the application of medical devices are numerous, the most used is the hemodialysate pipeline. At present, the multiporous structure of PTFE is more and more used in medicine, including for soft tissue regeneration of mesh and artificial blood vessels, as well as for heart, blood vessels, plastic surgery, general surgery, surgical suture and so on.
