The dust removal efficiency of ptfe reusable mask filter membrane can reach more than 99.9995%.
The minimum pore size of the film can reach 0.1um, which can capture most solid particles and liquid droplets. Since the pore size of the mask film is much larger than water vapor molecules, and polytetrafluoroethylene is a hydrophobic material, water droplets cannot penetrate the micropores, so Has good moisture permeability, breathability and waterproof properties.
The melting point is 164~170℃, and the products can be sterilized at temperatures above 100℃.
It has a complete set of domestic advanced production equipment and adopts advanced production technology. Its products have passed ISO9001 quality management system certification. The testing standards strictly follow the EU standard EN1822. Membrane products are tested using the MPPS method.
