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.
PTFE Material Properties
| Tensile Strength | Flexural Modulus | Tensile Elongation | Coefficient of Friction | Melting Point | Upper Service Temperature | |
|---|---|---|---|---|---|---|
| Test Method | ASTM D638 | ASTM D790 | ASTM D638 | ASTM D1894 | ASTM D3418 | UL746B |
| Teflon PTFE | 3,000 - 5,000 psi | 72,000 psi | 300 - 500% | 0.1 <10 ft./min | 621°F | 500°F |
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
- Hinges
- Food processing equipment
- Lab instrumentation
