Polytetrafluoroethylene (PTFE), commonly known by its trade name Teflon, is a versatile and highly desirable material for CNC machining due to its unique properties. It is a type of fluoropolymer and is best known for its non-stick and low-friction properties. This makes it an excellent choice for applications that require a low coefficient of friction, such as bearings, bushings, and seals. PTFE also has excellent chemical resistance, making it ideal for use in harsh environments.
Additionally, PTFE has a wide temperature range, from -200°C to +260°C, which makes it suitable for applications that require extreme temperature resistance. Its electrical insulation properties are also noteworthy, making it useful in electrical components and insulation.
- Low friction and wear resistance
- Highly machinable
