Did you know that the biaxial stretching process of porous polytetrafluoroethylene membrane gives the film good void characteristics, and the film in different directions is After stretching, the structure of the film’s micropores and agglomerates has changed, and at the same time, the mechanical properties of the film have anisotropic characteristics. Let’s learn more about it in detail.
In the field of water treatment, biomimetic water channel porous membranes inspired by unique water channels in cell membranes have higher water flux and desalination efficiency than traditional reverse osmosis membranes ; Biomimetic liquid-gated membrane inspired by alveoli has excellent oil/water separation performance and anti-fouling properties.
porous polytetrafluoroethylene membrane has excellent properties such as waterproofing, moisture permeability, air permeability, corrosion resistance, aging resistance, and high temperature resistance. . According to the usage requirements, the pore diameter of this microporous membrane can be between 0.1-1um, the thickness can be between 10-100um, the porosity can reach 50%-90%, and there are hundreds of millions of micropores per square centimeter. Since the pore size of the microporous membrane is much larger than that of water vapor molecules, and polytetrafluoroethylene (PTFE) is a hydrophobic material, water droplets cannot penetrate the micropores, so it has good moisture permeability, air permeability and waterproofness. The microporous membrane can withstand water pressure up to 0.1 MPa. Polytetrafluoroethylene (PTFE) also has excellent corrosion resistance, aging resistance and high temperature resistance, and its operating temperature can reach -150℃-250℃.
The porous polytetrafluoroethylene membrane produced by the manufacturer uses imported raw materials and has a full set of advanced production equipment. It has an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe film; it uses production testing instruments imported from the United States to test the quality of ptfe film, and has passed international SGS testing and certification, as well as ISI testing and certification.
