1. Acidity and alkalinity: neutral.

2. Corrosion resistance: It exhibits inertness towards most chemicals and solvents, and can withstand strong acids, alkalis, water, and various organic solvents.

3. Acid and alkali resistance: insoluble in strong acids, strong bases, and organic solvents.

4. Non adhesive: Solid materials have small surface tension and do not adhere to any substance.

5. Permeability: After long-term exposure to the atmosphere, the surface and properties remain unchanged.

6. Non combustibility: The oxygen limit index is below 90.

7. Antioxidant properties: able to withstand corrosion from strong oxidants.
