The porosity of the ptfe sterilization filter membrane can reach 80%~90%, the filtration efficiency can reach 99.999995%, it has strong hydrophobicity, low surface energy, good non-adhesion, and can easily remove dust accumulated on the surface of the material. , can be reused, greatly extending the service life. The filter membrane has very fine and smooth surface fibers and a small friction coefficient, so it is not easy to get dust. And due to its hydrophobic and stable chemical properties, the dust accumulated on the surface is easily absorbed. After cleaning, dust has a hard time sticking to it, even when wet.
