We always have a variety of filters in the laboratory to meet different needs.
So you know what are the most important considerations when choosing a filter? Of course, it is the filter membrane’s ability to withstand contact with fluids, and whether the filter is acid-resistant, alkali-resistant, or organic solvent-resistant, which is very important.
PTFE gray film just meets the above requirements.
After modification and compounding, the ePTFE membrane can have special properties in acoustic, electrical, magnetic, thermal, weather and chemical resistance, etc. Therefore, it is a new material with a very wide range of applications.
In the context of the country’s vigorous development of high-tech industries and promotion of industrial structural adjustment, industry development is mainly affected by the country’s relevant industry support policies.
The filtration mechanism of ptfe gray membrane is surface filtration mechanism, which can easily remove dust. The membrane pore size is small and uniform, the micropore structure is stable, the porosity can reach 80%~90%, the filtration efficiency can reach 99.999995%, and the filtration accuracy can reach Above U15 level, even up to U17 level.
At the same time, the surface is water-repellent and has a very high water pressure resistance, so it has high waterproof performance.
The protection against viruses in liquids is mainly based on the low surface tension of the PTFE film and the high water pressure resistance of the composite film, making it difficult for droplets to adhere, wet or penetrate.
