CNC Machining PMMA

Polytetrafluoroethylene(Teflon/PTFE) is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent corrosion resistance and is one of the best corrosion-resistant materials in the world today. It is resistant to all other chemicals except molten metal sodium and liquid fluorine. Boiling in water does not change, and it is widely used in various products that need to resist acids, alkalis and organic solvents. At the same time, it also has excellent chemical stability, sealing, high lubricity and non-stickiness, electrical insulation and good anti-aging endurance, and excellent temperature resistance (can work for a long time at a temperature of +250°C to -180°C). Machining teflon plastic material can be in the bar or plate shape, which allows teflon can be machined by cnc milling, cnc drilling and cnc lathing, etc.

The Advantages of Teflon Plastics


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.

Common Application Industries of Teflon/PTFE Machined Parts 


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.


  • Chemical Industry

    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.


  • Machinery Industry

    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.


  • Medical industry

    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.
