PTFE CNC Machining
PTFE, or Teflon, offers excellent chemical resistance and unmatched coefficient of friction
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.
