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 purification and ventilation purposes.
The ptfe materials produced by the manufacturer are all imported raw materials, and have a full set of advanced production equipment, advanced clean rooms and independent composite slitting workshops to ensure the production quality of ptfe membranes.
