How efficient are materials like washable mask membranes?

PTFE washable mask film adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods.

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.

It is a manufacturer of polytetrafluoroethylene (ptfe) membrane environmentally friendly materials that specializes in R&D, production and sales.
