Did you know that the biaxial stretching process of ptfe hydrophilic film gives the film good void characteristics, and films in different directions are stretched Finally, the structure of the film’s micropores and agglomerations has changed, and at the same time, the mechanical properties of the film have anisotropic characteristics. Let’s learn more about it in detail.
The pore size of the sterilizing filter membrane used in pharmaceutical production generally does not exceed 0.22μm. The pore size of a filter is defined by the filter’s retention of microorganisms, rather than the distribution coefficient of the average pore size. Therefore, the filter used for final sterilization needs to choose a sterilizing grade filter with retention test proof.
The currently independently developed ptfe hydrophilic membrane series is widely used in organic solvent filtration and has both hydrophobic and hydrophilic properties. categories. It can achieve sterility when used for gas filtration, has the characteristics of large flux, temperature resistance, resistance to strong acids and alkalis, and wide chemical applicability. It is suitable for fermentation tanks, carbon dioxide, nitrogen and compressed air. When used for liquid filtration, it can intercept all kinds of phages, small bacteria and particles above 0.2μm, meeting the requirements of HIMA small bacteria interception experiments.
