How is the disposable medical mask filter material made?

The filter material for disposable medical masks is made of polytetrafluoroethylene. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process. Becoming a new type of filter material, the membrane has small pore size (0.05~0.45μm), uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation.

It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.

The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
