PTFE (polytetrafluoroethylene, PTFE) is a high performance engineering plastic with unique physical and chemical properties, so it has the following advantages in Machined products:
1.Excellent chemical stability: Corrosion resistant parts in Chemical industry, Pharmaceutical industry and other fields.
2.Very low friction coefficient: Manufacturing Bearings, Sliders, seals and other parts.

3.Excellent resistance to high and low temperatures: Seals, Gaskets and so on suitable for extreme temperature environment.
4.Good electrical insulation: Suitable for high frequency electronic components, cable insulation layer, etc.
5. Non-stick: Suitable for manufacturing non-stick coatings, food processing equipment, etc.

6.Self-lubricating: Mechanical parts suitable for oil-free lubrication environment.
7.Good mechanical processing properties:Often used for customized seals, gaskets, bushings, etc.
8.Low water absorption:Sealing and insulating components suitable for wet or underwater environments.
9. Aging resistance:Suitable for outdoor or long-term exposure to harsh environments.


PTFE CNC parts are widely used in chemical industry, electronics, machinery, food and medicine, aerospace, construction, automobile and home appliances because of their corrosion resistance, high temperature resistance, low friction and insulation.
- Corrosion resistant equipment : used to manufacture pipes, valves, pumps, seals and so on, can withstand strong acids, strong alkalis and organic solvents.
- Liner material : as liner for reactor and storage tank to prevent corrosion.
- High frequency equipment : Insulation components for high frequency communication equipment.
- Seals : used for mechanical seals, piston rings, etc., heat resistant and corrosion resistant.
- Medical equipment : Seals and pipes for pharmaceutical equipment, corrosion resistant and non-toxic.
- Lubricating materials : lubricated parts used in high and low temperature environments.
- Weathering materials : weathering parts used in outdoor buildings.
- Insulation components : used for electrical insulation and heat resistance.
