Characteristic of PTFE:
1. Appearance of pure white;
2. High temperature: the use of temperature -200 ~ +250 degree; hot plate can be short-term resistance to 300 degree, open fire in the asbestos to be used;
3. Low-temperature resistance: a good mechanical toughness, even if the temperature dropped to -196 degree, 5% can also maintain the application rate;
4. Corrosion resistance: For most of the chemicals and solvents, showing inertia, the ability of strong acid and alkali, aqua regia and a variety of organic solvents;
5. Non-adhesion: with a solid material in the smallest surface tension, does not adhere to any substance;
6. High lubrication: the friction coefficient of the solid material (0.04) at the end;
7. Weather resistance: long-term exposure to the atmosphere, the surface and performance of the same, B068 plastic in the best aging life;
8. Anti-pollution: low blank value of metal elements, lead content of less than 10-11 g / ml, uranium content of less than 10-12 g / ml;
9. Non-toxic: a physiological inertia, as artificial blood vessels and organs long-term implantation of the body without adverse reactions.
