Polytetrafluoroethylene, also known as PTFE, (commonly known as the King of Plastics), was accidentally discovered by chemist Dr. Roy Plunkett in 1938. When he was trying to make a new chlorofluorocarbon refrigerant, PTFE Ethylene is polymerized in high-pressure storage vessels.
DuPont registered a trademark under the name “Teflon” in 1944.
In China, due to the pronunciation, the trademark “Teflon” is also called “Teflon”.
PTFE microporous membrane is used for air filtration, with a thickness of about 0.01mm and air permeability of 60-80L/m2.s. It has smooth surface, chemical resistance, air permeability and water impermeability, large air permeability, flame retardant, high temperature resistance, and With strong acid and alkali, non-toxic and other characteristics, it is widely used in flue gas dust removal and filtration in various industrial furnaces such as chemical industry, steel, metallurgy, carbon black, power generation, cement, and waste incineration; PTFE microporous membrane is used for purification and filtration: the thickness is 0.02-0.03mm, bubble point ≥1kg/cm2 (5.3m/s127Pa), widely used in pharmaceutical, biochemical, microelectronics and laboratory consumables and other fields; dust-free workshops, laboratories, ventilation equipment, purification equipment, medical electronics, etc. Air purification industry.
