Do you know the material of clean room FFU filter membrane, and do you know its specific functions and advantages? Today I will take you to learn about this material.
Polytetrafluoroethylene (PTFE) material, commonly known as the “king of plastics”, is a polymer compound polymerized by tetrafluoroethylene. It has excellent high temperature resistance, oxidation resistance, alkali resistance, hydrophobicity, and non-adhesion performance.
The clean room FFU filter membrane is prepared by a biaxial stretching process. It has a microporous structure with staggered fibers. It has high porosity, small and uniform pore size. Therefore, the polytetrafluoroethylene microporous membrane has a lower resistance under lower resistance. You can achieve higher efficiency.
my country has also begun to develop PTFE stretched membranes since the 1970s, but it has been stuck in the uniaxial stretching process for a long time. Since the 1990s, individual units have developed and produced biaxially stretched microfiltration membranes. Membrane products are mostly focused on the development of waterproof and breathable textiles [4,5]. In order to produce high-quality biaxially stretched PTFE microporous membranes, we paid special attention to the relationship between various factors and membrane pore performance and morphological structure during the development process. , to optimize the production process conditions, the clean room FFU filter membrane made by mechanical stretching ptfe material by Suzhou ptfe filter membrane manufacturer can ensure the complete retention of bacteria and other impurities, and at the same time have a large flux.
The material is resistant to high temperatures, strong acids and alkalis, 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.
