As long as the polytetrafluoroethylene mask film is added to the mask, it can effectively block small particles in the air and even some bacteria that are invisible to the human eye.
PTFE membrane, also known as polytetrafluoroethylene film, has a three-dimensional network structure, no through holes, and a high porosity, with the opening rate generally between 80% and 95%.
Furthermore, the filtration principle of this membrane is surface filtration, with low filtration resistance, which can block harmful gases in the air from the outside and ensure that they are not inhaled by the human body.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The products produced by our company have high uniformity, stable performance and good breathability.
