Fluoroplastic series popular science knowledge 1: Polytetrafluoroethylene (PTFE) properties, applications, manufacturers and commonly used models

Fluoroplastics are a type of polymer material with excellent chemical stability and high temperature resistance. The main fluoroplastics include polytetrafluoroethylene (PTFE), polyfluoroethylene copolymer (FEP), polychlorotrifluoroethylene (PCTFE), polyfluoropropylene (PFA), fluorine rubber (FKM), etc. The following are some of the main properties, application ranges and characteristics of these fluoroplastics:

Polytetrafluoroethylene (PTFE) is a high-performance plastic with special properties. The following are its main properties and applications:


High temperature resistance: PTFE has excellent high temperature resistance and can operate in the range of -200°C to +260°C, and can remain relatively stable even at higher temperatures.

Chemical resistance: PTFE shows high corrosion resistance to most chemical substances, including acids, alkalis, solvents, etc. It is an inert material that does not react easily with other chemicals.

Non-adhesion: PTFE is a material with excellent non-adhesion properties, making it an ideal material for coating cooking utensils, rails, valves, etc.

Electrical insulation: PTFE is an excellent electrical insulation material with good electrical properties.

Low coefficient of friction: Its low coefficient of friction makes PTFE widely used in bearings, seals and other applications where friction needs to be reduced.

Flexibility: PTFE remains flexible at low temperatures and does not become brittle easily.


Seals and Gaskets: Due to its non-adhesion and chemical resistance, PTFE is often used as seals and gaskets, especially in the chemical industry.

Electrical Insulating Parts: The electrical insulating properties of PTFE make it ideal for electrical insulating parts such as cable insulation, connectors and electronic components.

Valves and Pipes: Due to its corrosion resistance and high temperature resistance, PTFE is often used to make seals for valves and pipe systems.

Cooking utensils: PTFE is widely used to coat cooking utensils, such as non-stick pans, to provide superior non-stick properties.

Bearings and sliding parts: Low friction coefficient and wear resistance make PTFE used in manufacturing bearings, sliding parts and guide rails.

Chemical equipment: Due to its excellent chemical stability, PTFE is often used to manufacture chemical equipment, such as reactors, pipes, and pumps.
