Features of Extrusion PTFE rod:

1. White solid at room temperature, with a density of about 2200 kg/m3

2. High melting point is 600 K (327 °C; 620 °F)

3. Maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (−268.15 °C; −450.67 °F)

4. Good flexibility at temperatures above 194 K (−79 °C; −110 °F)

5. Gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons

6. Excellent dielectric properties, especially at high radio frequencies

7. Low friction, extremely high bulk resistivity

8. Extreme non-reactivity and high temperature rating
