PTFE nanomask filter membrane is a PTFE film prepared by one-way or two-way stretching method. The surface has a spider web-like microporous structure. The three-dimensional structure has network-like connections, hole nesting, and channel bending. Complex changes and therefore excellent surface filtration capabilities.
The surface of the ptfe nanomask 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. This film is laminated on various fabrics and substrates using a special process. material, it can become a new type of filter material.
