The kn95 mask filter membrane adopts a special processing technology and is a microporous film made by calendering, extrusion, and biaxial stretching.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
Three-dimensional mesh structure, no through holes.
The porosity and pore size distribution are important indicators for measuring films.
The filtration efficiency of the kn95 mask filter membrane can reach more than 95% for bacteria and PM2.5 particles in the air, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception. The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.
The manufacturer has a full set of advanced production equipment and technology, as well as an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the product materials produced are all imported raw materials with high uniformity. Stable performance and good breathability.
