1. High chemical stability
Teflon parts can withstand the action of all strong acids, strong alkalis, strong oxidants, reducing agents, etc. except molten alkali metals, fluorine elements, strong fluorinated media, and sodium hydroxide above 300 °C. Its chemical corrosion resistance exceeds that of precious metals, glass, ceramics, enamel and alloys, and even uranium fluoride, a strong corrosive agent in the atomic energy industry, does not corrode it.
2. Excellent high and low temperature resistance
PTFE parts can be used in a wide range of -250 to 260°C, and can still maintain a certain degree of flexibility even at an ultra-low temperature of -260°C; at 260°C, its breaking strength still maintains about 5 MPa (about 1 /5), the yield strength reaches 1.4MPa.
3. Outstanding non-stick
Teflon is a solid material with the smallest surface energy known so far. The surface tension is only 0.019N/m. Almost all solid materials cannot adhere to its surface. Only liquids with a surface tension below 0.02N/m can completely infiltrate it. surface.
4. Extraordinary self-lubrication
Due to the small mutual attraction between PTFE macromolecules and the small surface attraction to other molecules, its friction coefficient is very small, and it is the self-lubricating material with the lowest friction coefficient found so far.
5. Excellent electrical insulation properties
PTFE is a highly non-polar material with excellent dielectric properties and excellent arc resistance. When it is discharged at high voltage, it only releases some cracked non-conductive gas without carbonization causing short circuit. It has excellent dielectric properties, and its breakdown voltage is 25-40kV/mm; its resistance is extremely large, and its volume specific resistance is still as high as 1016Ψ·cm at 200°C.
6. Excellent aging resistance and radiation resistance
There is no photosensitive group in the PTFE molecule, so it is not only stable in size at low temperature and high temperature, but also has the same performance in harsh environments.
7. Minimal water absorption
The water absorption rate of Teflon is generally about 0.001% to 0.005%, and its permeability is also low.
PTFE / Teflon has the above advantages, making it an anti-corrosion and friction material that cannot be replaced by other materials.

Teflon is one of the most important plastics. It has a series of unique properties such as wide temperature range (-250~260°C), good chemical stability, excellent dielectric properties, self-lubrication and anti-sticking properties, so PTFE machined parts have a wide range of applications.
PTFE can be used as an anti-corrosion material to manufacture various anti-corrosion parts, such as pipes, valves, pumps and fittings. In terms of chemical equipment, it can be used to make linings and coatings for reactors, distillation towers and anti-corrosion equipment.
Teflon can be used to machine parts such as self-lubricating bearings, piston rings, oil seals and sealing rings. Machined Teflon parts are self-lubricating, reducing mechanical wear and heat, and reduce power consumption.
Electronic and electrical industry
PTFE is mainly used in the manufacture of various wires and cables, battery electrodes, battery separators, printed circuit boards, etc.
In the medical industry, its heat-resistant, water-resistant, and non-toxic properties can be used as materials for various medical devices and artificial organs.
