The kn95 mask filter membrane 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. 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.
It is a high-tech enterprise specializing in the research and development, production and sales of polytetrafluoroethylene microporous membranes. It has advanced ptfe membrane production lines, coating and composite production lines, which are at the domestic advanced level.
