The pore size of PTFE microporous membrane is small
Due to the continuous development of industrial processes, the continuous improvement of people’s living standards, and the continuous improvement of environmental awareness and requirements, my country’s filter element market has also gradually developed and improved. Many new filter materials (especially air filtration, water filtration, etc.) are emerging in endlessly. Polytetrafluoroethylene microporous membrane is a product of the new era.
The ePTFE microporous film has good thermal stability and a wide operating temperature. It can work continuously at a low temperature of minus 200℃ to a high temperature of above zero 260℃, with a melting point as high as 327℃, non-flammable, excellent chemical stability, good acid and alkali resistance, able to withstand many highly corrosive media, small friction coefficient, and strong hydrophobicity. The pore size is small (average pore size 0.2mm), blocking the penetration of certain toxic gases or aerosols, and the low surface can prevent the penetration of certain toxic liquids.
Polytetrafluoroethylene microporous membraneThe porosity can reach more than 85%, and the air can flow smoothly. The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above. Protect electronic instruments from becoming unusable due to moisture or water. Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
The PTFE microporous membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency , for some very small particles with a diameter of 0.1um-0.3um, the filtration level can reach H13-U16.
