Porosity of PTFE bubble point membrane
Do you know the material PTFE bubble film? Do you know what it is used for? Today I will take you to learn about this material.
PTFE bubble point film is made of dispersed PTFE resin powder as raw material and stretched through a series of special processes. It has a fibrillar microporous structure with a porosity of more than 85% and 1.4 billion micropores per square centimeter. Hole, pore diameter range 0.02um-1.5um.
Industrial manufacturing or air purification and filtration and other areas will require the use of filter materials.
This membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency, and ultra high efficiency air filters.
The PTFE bubble point film itself has countless interconnected micropores. The pore diameter is very fine and can only pass through water vapor molecules with a particle size of about 0.1nm. However, for any raindrops or water droplets, because their particle size is too large, and cannot pass.
In this way, water vapor emitted by the human body can effectively diffuse outward through the pores, while water droplets cannot penetrate inward, thus achieving a waterproof and moisture-permeable effect.
We are a manufacturer specializing in the production of polytetrafluoroethylene membrane materials. The ptfe bubble-point membrane we produce has the characteristics of stable chemical properties, high filtration efficiency, easy cleaning, high temperature resistance, corrosion resistance, etc.
The main principle of this membrane is to control the pore size of the membrane. The higher the bubble point, the smaller the pore size of the membrane, and the lower the bubble point, the larger the pore size of the membrane.
It has high porosity and small and uniform pore diameter. Therefore, the PTFE bubble-point membrane can achieve higher efficiency with lower resistance. It can not only effectively intercept dust particles, but the highest accuracy can reach H14 level or above. .
We have a complete pre-sales, sales and after-sales service system.
