In the face of the COVID-19 epidemic, we now wear masks every day when we go out. Do you know what the core materials of masks are? Let’s take a closer look at the PTFE medical mask filter material.
Currently, the filter layer used for masks is mainly polypropylene (PP) melt-blown non-woven fabric, which is composed of fibers accumulated to form a network-like through-structure, so it has good filtering properties, barrier properties, heat preservation and adsorption properties.
The size of PP melt-blown non-woven fibers on the market is 1-10μm, which cannot reach the nanometer level. The pores formed by fiber accumulation are large and cannot effectively collect small particles. The filtration efficiency of 0.3μm particles is in Below 50%.
The porosity of ptfe medical mask filter material can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um, and has high and low temperature resistance ( -200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
It can ensure complete retention of bacteria and other impurities while having a large flux.
PTFE film manufacturer specializes in the production of PTFE medical mask filter materials. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the product materials produced They all use imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
The company has a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
