What about the material of washable mask membrane?

The washable mask film is made of polytetrafluoroethylene as raw material. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process to become a new type of mask film. 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.

The PTFE materials produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the production quality of PTFE membranes.
