What are the characteristics of masks produced using PTFE mask film?

Nano masks can also be called PTFE nano film masks. The special feature is that the middle layer is made of nano films with smaller pores (100-200 nanometers). Nano masks produced using PTFE mask films have high barrier efficiency. The characteristics of long service life, lightness and breathability are the new direction for the development of masks in the future.

But at present, this kind of mask is relatively expensive and cannot completely replace traditional masks.

The polytetrafluoroethylene microporous membrane is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.
