I don’t know how much you know about PTFE bubble film composite materials. Today I will give you some knowledge. Let’s learn about this new type of material.
For microbial retention tests, a filter membrane with a pore size of 0.45 microns should be selected as the positive control for each test.
The size of the challenge microorganism needs to be able to penetrate a 0.45 micron filter to demonstrate that it is cultured to the appropriate size and concentration.
Three different batch numbers of 0.22 micron (or 0.2 micron) test filter membranes and 0.45 micron control filter membranes need to be challenged online in parallel in a test system.
PTFE bubble point membrane composite material is a membrane material with excellent performance for filtering and separating microparticles.
It can be used for atmospheric dust removal, air purification, etc. The pore size of the membrane can be controlled to 0.2um, and the porosity can reach more than 88%. It is compounded with various filter materials such as needle felt, machine-made cloth, non-woven fabric, glass fiber, etc. The film-coated filter material with surface filtration performance makes the film-coated filter material have the characteristics of high peel strength, large air permeability, and uniform pore size distribution.
