Polytetrafluoroethylene, also known as ptfe, is the originator of fluoroplastics, and the most unusual of the Fluoropolymer, showing the best performance in terms of temperature, chemical resistance and non stick properties. 



The properties of PTFE

A plastic molecule contains a carbon chain with hydrogen atoms attached to it. In the polytetrafluoroethylene structure, hydrogen atoms are replaced by fluorine atoms, which greatly changes the material’s properties. PTFE, like other fluoroplastics, has some special properties:

Extremely high operating temperature, non-stick characteristic, low friction surface, high tolerance to chemicals and solvents, extremely high resistance, weatherability, UV resistance and corrosion resistance, Inert, non-toxic, biocompatible.



What are the advantages of ptfe?

PTFE is the most unusual Fluoropolymer, showing the best performance in terms of temperature, chemical resistance and non-stick properties. In addition, polytetrafluoroethylene has the following advantages:

Best Value for money

Continuous operating temperature + 260 ° . This is the maximum operating temperature for all fluoroplastics

Tolerance to almost all chemicals.

Low friction surface

Extremely high resistance


What are the disadvantages of ptfe?

The main disadvantage of polytetrafluoroethylene is that they do not actually melt when heated, making them difficult to process. The molding, extrusion, and welding of the Fluoropolymer require very unconventional processes. Therefore, ptfe is hard to process.


What is the purpose of the ptfe ?

Due to its extraordinary performance, the ptfe can withstand even the harshest environments, so it is suitable for use in many applications. The fluoroplastics are ideal for food and beverage production, from cooking equipment to food coverings, conveyor belt rollers, temperature sensor housings, and nonstick surface coverings.


In addition to the food industry, in the chemical industry, polytetrafluoroethylene can be used to make a variety of products, from washers to container liners and chemical tanks. Polytetrafluoroethylene is also widely used in high temperature applications, from fire protection to heating elements and terminal insulation for jet engine, ultraviolet lamps and external aircraft fittings.



Polytetrafluoroethylene materials are ideal for medical applications and for the production of internal and external life saving devices such as catheters, biological containers, syringes and sutures. This unique Fluoropolymer is also perfect for electrical insulation and electronic component protection.


Fluoropolymer are woven into our daily lives in hundreds of ways. At home, non stick pans are made from polytetrafluoroethylene, and most razors contain a teflon based anti friction coating that covers everything from smartphones to laptops, and electrical equipment including polytetrafluoroethylene insulation.

Except foe these applications, ptfe are often made into ptfe tape which can help seal. Ptfe tape is a common thing in plumber connection and pipeline. It is quite easy for using. If you want to buy a ptfe tape, then you should come to our website. Foreverseal has focused on manufacturing ptfe tape products for many years and our products have high quality.
