The polytetrafluoroethylene mask film produced is made of ptfe resin as raw material and is made through special processes such as mixing, extrusion, extrusion, calendering, and bidirectional stretching. Its pore size, thickness, and void ratio can be determined according to Requires adjustment while stretching.
In addition, ptfe mask membrane can be applied to the surface of various filter materials through composite processing, thereby greatly improving the filtration accuracy and meeting the filtration efficiency level requirements of sub-high efficiency, high efficiency, and ultra-high efficiency air filters.
The respiratory impedance of polytetrafluoroethylene mask membrane is only 60-70pa, and the ordinary melt-blown non-woven mask is as high as 120-250pa. In comparison, the breathability of film masks is already very good, but it certainly cannot be compared. Wearing a mask vs.
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.
Have a group of professional polymer R&D teams, focusing on the research and development of polytetrafluoroethylene mask membrane technology; strong R&D capabilities, R&D and improvement technology research, and achieved effective results, with multiple invention patent certificates and practical patent certificates .
