Polytetrafluoroethylene mask film refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and through calendering, extrusion, biaxial stretching and other methods.
? 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 fluorine material film manufacturer integrating production, sales and customization.
Our company is different from other manufacturers. Our company can produce products according to user requirements.
The key to the technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
