Polytetrafluoroethylene mask membrane is often used in the production of medical masks. The results of some academic studies show that the use of this material can provide better filtration function, permeability, antibacterial and wear resistance.

Spunbonded nonwovens: spunbonded nonwovens use the principle of chemical fiber spinning to lay continuous filament fibers into a network in the process of polymer spinning, and the fiber network is made into cloth by mechanical, chemical or thermal bonding reinforcement. Its structural characteristics make the fiber network randomly composed of continuous filaments with good physical and mechanical properties.

The dust removal efficiency of PTFE mask film can reach more than 99.9995%. The minimum pore diameter of the membrane can reach 0.1um, which can capture most solid particles and droplets. Because the pore diameter of the mask membrane is much larger than that of water vapor molecules, and polytetrafluoroethylene is a hydrophobic material, water droplets cannot penetrate micropores, so it has good moisture permeability, air permeability and water resistance. The melting point is 164 ~ 170 ℃, and the products can be sterilized at a temperature above 100 ℃.
