The kn95 mask filter membrane is one of the materials with the best corrosion resistance in the world today. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it is resistant to all other chemical reactions and is insoluble in strong acids, strong alkali and organic solutions. It does not change in boiling nitrohydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
The respiratory impedance of the filter membrane of the kn95 mask is only 60-70pa, while the ordinary melt-blown non-woven mask is as high as 120-250pa. In comparison, the breathability of the film mask is already very good, but it certainly cannot be compared to not wearing a mask. Compare.
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.
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 materials; the product materials produced are all imported raw materials with high uniformity. Stable performance and good breathability.
