Polytetrafluoroethylene (ptfe) is well known to everyone. It is a material that is acid and alkali resistant and almost insoluble in all solvents.
In addition, ptfe is resistant to high temperatures, has an extremely low friction coefficient, and has self-cleaning characteristics. It is an ideal material for filtration. For more details, I will take you to the ptfe water-resistant filter membrane manufacturer to learn more.
Using the pore-forming properties of polytetrafluoroethylene plastic resin, it is a microporous film made by biaxial stretching method.
The surface of the membrane can reach more than one billion micropores per square centimeter. The diameter of each micropore (0.1μm-0.5μm) is hundreds of times smaller than the diameter of water molecules (20μm-100μm) and smaller than the diameter of water vapor molecules (0.0003 μm-0.0004μm) is tens of thousands times larger, allowing water vapor to pass through, but water droplets cannot pass through. This microporous structure can be used to achieve excellent waterproof and breathable functions.
The filtration efficiency of ptfe washable filter membrane for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception. The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.
It is an environmentally friendly material manufacturer specializing in R&D, production and sales of ptfe water-resistant filter membranes.
