Suzhou ptfe reusable mask filter membrane

Do you know what ptfe reusable mask filter is? And what material is ptfe? What advantages and performance does it have? What are its uses? Don’t be anxious, please listen to the editor slowly introduce this material to you.

PTFE membrane is a microporous film made of polytetrafluoroethylene as raw material, using a special process, calendering, extrusion, biaxial stretching and other methods.

PTFE membranes can be divided into clothing membranes, air filtration membranes, and air purification membranes according to their uses.

PTFE membrane has a fibrillar microporous structure with a porosity of more than 85%, 1.4 billion micropores per square centimeter, and a pore size range of 0.02μm-15μm.

The ptfe reusable mask filter membrane can filter more than 95% of bacteria and PM2.5 particles in the air, 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 (pore size interception method). 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.

The PTFE reusable mask filter membrane made by the Suzhou PTFE filter membrane manufacturer by mechanically stretching PTFE material can ensure the complete retention of impurities such as bacteria and has a large flux.

The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.

PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
