We all know that the materials required to make traditional masks are generally ordinary non-woven fabrics, cotton or gauze.
Scientific research has found that as long as the polytetrafluoroethylene mask film is added to the mask, it can effectively block small particles in the air, and even some bacteria that are invisible to the human eye.
The polytetrafluoroethylene mask membrane made by the Suzhou ptfe filter membrane manufacturer by mechanically stretching ptfe material can ensure the complete retention of bacteria and other impurities, while having a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
The polytetrafluoroethylene microporous membrane has a very high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency, and ultra-high efficiency air filters? The respiratory impedance of the polytetrafluoroethylene mask membrane is only 60-70pa. Ordinary The melt-blown non-woven masks have a density of 120-250pa. In comparison, the breathability of film masks is already very good, but it certainly cannot be compared to not wearing a mask.
The wearing comfort of a polytetrafluoroethylene film mask is mainly determined by the air permeability and moisture permeability of the mask.
Thin film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of film materials, they can give users a more comfortable breathing experience.
