FFU is the abbreviation of FANFILTERUNIT. It is called “fan filter unit” in Chinese, which means that the fan and filter are combined together to form a terminal purification equipment that can provide power by itself. What we are going to talk about today is one of them. Core material: clean room FFU filter membrane.
The development of clean rooms is closely linked to modern industry and cutting-edge technology.
Due to the environmental requirements of the precision machinery industry (such as gyroscopes, micro bearings, etc. processing) and the semiconductor industry (such as large-scale integrated circuit production), the development of clean room technology has been promoted.
Domestic statistics have shown that the pass rate of MOS circuit dies produced in an environment without clean level requirements is only 10% to 15%, and the 64-bit memory is only 2%.
Clean rooms are currently widely used in industries such as precision machinery, semiconductors, aerospace, and atomic energy.
Clean room FFU filter membrane is a polymer compound of tetrafluoroethylene. It is one of the materials with the best corrosion resistance in the world. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it can withstand all other chemical reactions. , insoluble in strong acids, strong alkali and organic solutions, and does not change in boiling nitrohydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
It is an environmentally friendly filter material manufacturer specializing in R&D, customization, production and sales of clean room FFU filter membranes.
