1. Except hydrofluoric acid and concentrated alkali, it has extremely good corrosion resistance to all corrosive liquids;
2. Good heat resistance, no thermal deformation, softening, oxidation, can be used at higher temperatures;
3. The gas distribution is even, and a fine aperture of 0.1 ~ 600mm can be formed as required;
4. High rigidity, does not cause shape change and pore deformation under the action of fluid pressure;
5. There is no exudate in the liquid, which will not pollute the liquid.
