PTFE liquid filtration membrane is made of PTFE as raw material. It is biaxially stretched through a special process and utilizes the unique node fibrillarity of polytetrafluoroethylene film, smooth surface, chemical resistance, air permeability and water impermeability, large air permeability, and flame retardant. , high temperature resistance, resistance to strong acid and alkali, non-toxic and other characteristics, the products made have high filtration efficiency, up to 99.99%, close to zero emissions; low operating resistance, fast filtration speed; long service life and can be reused.
PTFE liquid filtration membranes are generally divided into the following types: air filtration membranes, which can be used for atmospheric dust removal, air purification, etc., and are the best filter materials for various vacuum cleaners, air filters, and purification equipment; waterproof and moisture-permeable microporous membranes , which is characterized by good wind resistance and warmth retention, and is widely used in medical, fire-fighting, anti-virus, water-immersed clothing, outdoor sleeping bags, tents, etc.; this film is laminated on various fabrics and substrates using special processes to become a new filter material. The membrane pore size is small, about 0.2-0.5μm, evenly distributed, and has a large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve advanced purification and ventilation purposes. It is widely used in pharmaceuticals, Biochemical, microelectronics and laboratory consumables and other fields.
