How about the PTFE nano mask cloth in terms of bacterial filtration?
PTFE nano mask cloth can ensure complete interception of bacteria and other impurities while having a large flux. The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical …
What is the protective effect of ptfe nano mask cloth?
The filtration efficiency of ptfe nano mask cloth 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 and ultra-thin …
What is the protective effect of ptfe nano mask cloth?
The filtration efficiency of ptfe nano mask cloth 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 and ultra-thin …
What is the respiratory impedance of ptfe nano mask cloth?
The respiratory impedance of ptfe nano mask cloth is only 60-70pa, while ordinary melt-blown non-woven masks are as high as 120-250pa. In comparison, the breathability of film masks is already very good, but it…
What is the approximate filtration efficiency of ptfe nano mask cloth?
The filtration efficiency of ptfe nano mask cloth for bacteria and PM2.5 particles in the air can reach more than 95%. The extremely high porosity and ultra-thin thickness of <5μm make it have better air per…
Are masks made of ptfe nano mask cloth good?
PTFE nano mask cloth is a purely physical barrier and does not rely on static electricity. When the user inhales, the pores of 100~200 nanometers will block PM2.5 to PM0.3 through physical screening and block i…
What are the characteristics of ptfe nano mask cloth?
PTFE nano mask cloth is a microporous film made by calendering, extrusion, biaxial stretching and other methods using a special processing technology. This kind of membrane has excellent breathability, corrosio…

Is PTFE bubble point membrane an asymmetric porous membrane?
PTFE bubble point membrane usually refers to an asymmetric porous membrane with a surface pore diameter of 20~50nm and a wide range of molecular mass interceptions, from thousands to hundreds of thousands u [1]…
What do you need to know about PTFE bubble point filter media?
The main principle of ptfe bubble point filter material is to control the pore size of the membrane. The higher the bubble point, the smaller the pore size of the membrane, and the lower the bubble point, the l…
What is the pore size range of PTFE bubble point membrane?
The pore size of the ptfe bubble point membrane ranges from nanometer to nanoscale, and it can intercept substances with relative molecular masses between 100 and 1000. It is a membrane process between reverse …
