With the emergence of the new type of pneumonia, masks are now the most popular ones, protecting the health of everyone and the medical staff fighting on the front line. Do you know what materials they are made of? The answer is simple, that is ptfe nano mask cloth.
PTFE nano mask cloth is a microporous film made by special processing technology, such as calendering, extrusion, and biaxial stretching.
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.
