Clean room FFU filter membrane processing technology

Generally speaking, Clean room FFU filter membrane can remove particulates, harmful air, bacteria and other pollutants in the air within a certain range, thereby Ensure that the production process will not be affected.

Science and technology are developing rapidly, and high-tech products are constantly emerging, especially in the electronics industry The development of integrated circuits is changing with each passing day. For example, the development of integrated circuits is updated to a new generation every two or three years. The development of IC chips follows “Moore’s Law” (predicted by Gordon E. Moore, co-founder of Intel in 1965). The number of transistors that can be accommodated on a chip (ie, the degree of integration) can double every 18 months.

Clean roomFFU filter membrane refers to polytetrafluoroethylene as raw material and using special processing technology , a microporous film made by calendering, extrusion, biaxial stretching and other methods. This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties. According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.

Clean room FFU filter membrane is prepared using unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities, while also having Larger flux. The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um. PTFE microporous 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.
