PTFE is a crystalline polymer with chemical resistance and a coefficient of friction lower than nearly any other materials. The dialectric constant (2.1) of PTFE and its loss factor are low and stable across a wide temperature and frequency range.

Uses for CNC Machining PTFE
PTFE parts exhibit low coefficient of friction and chemical resistance. It's often used for industrial and electrical applications.
- Bearings and bushings
- Electrical housings
- Food processing equipment
- Lab instrumentation
