Children’s mask ptfe filter material is a microporous film made of polytetrafluoroethylene as raw material, using special technology, 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 filtration efficiency of the ptfe filter material of children’s masks can reach more than 95% for 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.
? is a manufacturer of polytetrafluoroethylene filter materials 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.
