PTFE Membrane Filters
PTFE Membrane Filters for filtration are made of PTFE (polytetrafluoroethylene) and were drawn 2-dimension. It is a micro-pore film. The PTFE membrane was laminated with a great variety of fabric and paper. Applied to extensive industries, including biochemistry, microelectronic, lab material and etc. Directly and indirectly related to pharmacy brewing, manufacture of pure water and special need water, beverage and dairy, chemical reagent, biochemical reagent, air filtration of fermentation tank in microelectronic, purification and filtration in microelectronic plants, filtration and separation of antibacterial fluid, production of medicine, air conditioning of hospitals and commercial buildings.
