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 disposable mask filter material.
The stretching process of PTFE is a process in which fine fibers are continuously pulled out from the folded lamellae and become longer and thinner.
During the uniaxial stretching (longitudinal stretching) process of the PTFE calendered film, the thin fibers are continuously pulled out, forming island-shaped nodes composed of unstretched crystal regions and slender fibers connecting the nodes. Nodes – fiber structure.
The surface of the disposable mask filter material is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2.5.
It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is laminated on various fabrics and substrates using a special process. material, it can become a new type of filter material.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the R&D, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, disposable mask filter materials, Teflon films and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
