Microporous filter material PTFE mask membrane

We often see doctors and nurses wearing masks, which is a layer of protection for medical staff.

With this layer of “white cloth”, they can be protected from viruses, bacteria and dust.

So do you know what materials these masks are made of? Very simple, it is a polytetrafluoroethylene mask film.

Polytetrafluoroethylene mask film is a microporous film made by calendering, extrusion, biaxial stretching and other methods using a special processing technology.

This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.

Three-dimensional mesh structure, no through holes.

The porosity and pore size distribution are important indicators for measuring films.

The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.

?Product quality is constantly improving, and it occupies a dominant position in the market with its unique and stable performance.

And it has a complete set of domestic advanced production lines, which can be customized according to user requirements.

The key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. are optimized and combined. According to the ratio and pore-forming medium, the air permeability, thickness and void ratio can be adjusted online to meet your different requirements. .
