Suzhou is a high-tech enterprise specializing in the research, development and production of fluorine material film technology. The ptfe bubble point film composite material developed by the company occupies a dominant position in the market with its unique stable performance. Let’s learn more about it together. have a look.
Whether membranes or filters are used in sterile filtration validation depends on the purpose of the validation.
If the purpose of the microbial retention test is to verify the bacterial retention efficiency of a specific membrane material in the filtration process, then the use of filter membranes can meet the needs.
The filter membrane used in the microbial retention test must be made of exactly the same material as the filter used in actual production, and should include multiple batches (usually three batches).
At least one batch should be a low bubble point (low specification) filter membrane.
PTFE bubble point film composite material is a polytetrafluoroethylene film that is biaxially stretched vertically and horizontally. It is a new material that is acid and alkali resistant and resistant to various organic solvents. It is almost insoluble in all solvents.
Its friction coefficient is extremely low, so it can be used for lubrication and is also an ideal coating for easy-to-clean woks and the inner layer of water pipes.
Therefore it is an indispensable product for aviation, navigation, aerospace, communications, electronics, military, weapons and other industries.
The ptfe bubble point film composite material produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely small particles with a diameter of 0.1um-0.3um For particles, the filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
