Waterproof and breathable PTFE bubble point membrane material has high porosity, uniform pore size distribution, breathability, small friction coefficient and minimal adsorption.
Excellent stretching technology can keep the micropore diameter between 0.1-0.1μm.
Far more than 10,000 times smaller than water droplets, the waterproof and breathable bubble dot film has excellent water-blocking properties. No matter how small water droplets are, they cannot pass through the film.
?The PTFE bubble point film itself has countless interconnected micropores. The pore diameter is very fine and can only pass through water vapor molecules with a particle size of about 0.1nm. However, for any raindrops or water droplets, due to their excessive particle size, Unable to pass.
In this way, water vapor emitted by the human body can effectively diffuse outward through the pores, while water droplets cannot penetrate inward, thus achieving a waterproof and moisture-permeable effect.
Polytetrafluoroethylene bubble point membrane has two categories: hydrophobic and hydrophilic: Hydrophobic: used for gas filtration to achieve sterility, large flux, high temperature resistance, strong acid and alkali resistance, wide chemical applicability, Suitable for fermentation tanks, carbon dioxide, nitrogen, compressed air.
When used for gas filtration, it can intercept 100% of various phages, bacteria and particles above 0.02um.
Hydrophilicity: used for liquid filtration to achieve sterility, wide chemical applicability, resistance to strong acids and alkali, and high ozone intensity.
