PTFE mask film meets the needs of many fields
The polytetrafluoroethylene mask membrane prepared by one-way or two-way stretching method has a spider web-like microporous structure on the surface. The three-dimensional structure has very complex changes such as network connectivity, hole nesting, and channel bending. , so it has excellent surface filtration function.
Nano masks produced using this material have the characteristics of high barrier efficiency, long service life, lightness and breathability, and are a new direction for the development of masks in the future.
?The English name of polytetrafluoroethylene is ptfe.
The surface of the polytetrafluoroethylene mask membrane 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.
? is a high-tech enterprise focusing on the research, development and production of fluorine material membrane technology. It is engaged in technology development, transfer, consulting and services in the field of new materials; R&D, production, sales and customization; and providing design solutions for high-efficiency separation and filtration materials. business.
