It is understood that the polytetrafluoroethylene mask membrane filters harmful outdoor particles through 400,000-600,000 micropores per square meter. The micropores are in the shape of a straight cone. The surface of the membrane is uniform and has a large tension, which reflects the particles in the air. Most of the harmful particles, coupled with the adsorption and blocking of particles by the unique micro-electric field on the membrane surface, effectively block outdoor PM2.5, with a blocking efficiency of up to 98%.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
