Polytetrafluoroethylene (PTFE) CNC Machining
Polytetrafluoroethylene (PTFE) is a fluoropolymer-based thermoplastic composed entirely of carbon and fluorine atoms, commonly known by the DuPont trade name Teflon. PTFE has the highest temperature resistance of all common engineering plastics and, due to its chemical composition, is extremely corrosion-resistant.
CNC machining of PTFE (Teflon) is relatively easy due to its low strength and relative flexibility. However, maintaining a high level of precision during machining can be challenging. Overall, PTFE is a high-quality material suitable for a variety of applications, particularly those requiring high-temperature and corrosion resistance.
Polytetrafluoroethylene (Teflon) differs from most engineering plastics due to its extremely high melting point, low coefficient of friction, and chemical inertness. These unique properties have made PTFE coatings widely used in non-stick cookware and various industries, including food and beverage, petrochemical, medical, and electrical components.
| Applications | Advantages | Disadvantages | Lead Time | Price | Tolerances |
|---|---|---|---|---|---|
|
Medical implants, pipe coatings for corrosive chemicals, electrical component insulation |
Food-safe, hydrophobic, high-temperature resistance, low friction coefficient |
Creates toxic fumes when overheated, poor abrasion resistance |
Lead times start at 3 days. |

Standard tolerance is +/- 0.010” ; +/- 0.001" tolerances are achievable. |
Virgin PTFE (Teflon)
Although polytetrafluoroethylene (PTFE, Teflon) is primarily used as a coating, some medical implants are manufactured through CNC machining of PTFE. Due to its inertness, medical implants made from this material are not rejected by the body. Furthermore, its low coefficient of friction makes it an ideal choice for sliding contact components, such as bearings, ensuring good performance and durability.
