Small and uniform aperture:

The pore size distribution of microporous membranes is very uniform, typically ranging from 0.1 micrometers to 10 micrometers. This uniform pore size distribution enables the microporous membrane to have a high screening effect during the filtration process, allowing for precise control of the particle size of the filtered material.

High interception capacity:

Due to its small and uniform pore size, microporous membranes can effectively trap suspended solids, bacteria, viruses, particles, and other impurities in water, with filtration accuracy meeting the requirements of sub high efficiency, high efficiency, and ultra high efficiency air filters.

Light and thin texture, low resistance:

The texture of microporous membrane is usually light and thin, with a thickness between 0.1~0.15mm, and a high porosity (microporous volume accounts for about 80% of the total volume). This makes the liquid medicine pass through the membrane with low resistance and fast filtration rate, which is 40 times faster than other filtration media with the same retention index.

No medium detachment:

A microporous membrane is a continuous whole that ensures the purity of the filtered liquid without any media shedding during the filtration process.

Good chemical stability:

Microporous filter membranes have good chemical stability and are not easily affected by chemical substances, making them suitable for filtering various chemical solvents. Partially made microporous membranes, such as polytetrafluoroethylene (PTFE) microporous membranes, also have characteristics such as corrosion resistance, high temperature resistance, and low friction, making them suitable for filtration applications in harsh environments.

Good biocompatibility:

Some microporous membrane materials, such as polypropylene (PP) membranes, have good biocompatibility and are suitable for filtration applications in medical, pharmaceutical, and other fields.

Wide application range:

Microporous filter membranes are widely used in various fields such as scientific research, food testing, chemical engineering, nanotechnology, energy, and environmental protection. In industries such as water treatment, air purification, pharmaceuticals, and electronics, microporous membranes play an irreplaceable role as key filtration materials.

Diverse structures:

From a structural analysis, the microporous membrane is an extremely thin membrane with a porous sponge like structure inside. According to their morphological differences, microporous filter membranes can be divided into various types such as flat thin paper filter membranes, hollow fiber filter membranes, and tubular filter membranes.

Easy to use and replace:

Microporous filter membranes are simple and fast to use, and are mostly disposable, making them easy to replace and handle.

It should be noted that although microporous membranes have many advantages, they also have some disadvantages, such as being prone to clogging, especially when dealing with liquids containing a large amount of suspended solids. In addition, some cellulose filter membranes may not have ideal stability under specific conditions. Therefore, when using microporous membranes, it is necessary to choose suitable materials and models according to specific application scenarios and requirements, and follow the correct usage and maintenance methods.
