What is the pore size range of ptfe water-resistant filter membrane material?

The surface of the ptfe water-resistant filter membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2.5.

It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm.

The polytetrafluoroethylene microporous membrane is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.

It can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
