The filtration efficiency of the ptfe nano mask filter membrane for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks. The extremely high porosity a…

The ptfe nanomask filter membrane has a fibrillar microporous structure. The porosity of the membrane can reach more than 88% or even higher. Moreover, the membrane has 1.4 billion micropores per square centime…

The imported dry-laid spunbond non-woven fabric dealer product is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the …

PTFE nano mask filter membrane can effectively prevent respiratory tract infections and prevent haze. The N95 mask is one of the nine types of anti-particle masks certified by NIOSH (National Institute of Occup…

With the increasing intensity of national environmental protection, the concept of green environmental protection has slowly become more and more popular and has been increasingly valued. Environmentally friend…

PTFE medical mask filter material uses physical barriers to air pollutants, so it is more durable. The ordinary non-woven fabric used in our traditional masks relies on static electricity to absorb particles in…

The surface of the ptfe medical mask filter material 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…

The fiber diameter of the ordinary non-woven material used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the ptfe medical mask filter material is between 100 and 200 nanomet…

A mask is a sanitary product that generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose to prevent harmful gases, odors, and droplets from entering and exiting th…
