Whenever smog comes, people wearing masks are everywhere in the streets and alleys. There are also many recommended masks on the Internet to prevent PM2.5, and the polytetrafluoroethylene mask film plays a huge role here. Below we Let’s take a closer look.
For the filter material of a good protective mask, it should meet the following three conditions. First, the filtration efficiency is high when the mask is in good contact with the user’s face. Second, the breathing resistance is small. Third, the user feels comfortable.
Dust-proof mask filter materials are made of a variety of materials, including ordinary fabrics, animal hair, non-woven fabrics, etc.
What is very popular in the national standard is an activated carbon felt material.
Polytetrafluoroethylene mask film is a microporous film made of polytetrafluoroethylene as raw material and using special processes such as calendering, extrusion, and biaxial stretching.
It has a microporous structure with staggered fibers. The porosity can reach 80%~90%. After high-temperature heat setting treatment, the microporous structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform, and the surface filters Mechanism, easy dust removal, strong hydrophobicity, low surface energy, good non-adhesive ability, and effectively remove dust accumulated on the surface.
It is a high-tech enterprise specializing in the research and development, production and sales of polytetrafluoroethylene mask films. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we The products produced are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
And we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
