Excellent performance of PTFE mask film
Polytetrafluoroethylene (PTFE) material, commonly known as the “king of plastics”, is a polymer compound polymerized by tetrafluoroethylene. The polytetrafluoroethylene mask film is prepared through a biaxial stretching process. It has high porosity. The pore size is small and uniform, resulting in higher efficiency with lower resistance.
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.
