2021/8/3 · The PTFE membranes also referred as Polytetrafluoroethylene membranes. These are non-reactive filter media used in various applications that involves acids, bases, solvents, and different liquids. Also, they are used in the industrial applications such as mineral production, temperature, humidity, power generation, and chemical processing to monitor standards for quality of product and

Polytetrafluoroethylene was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont.As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty." ." Since Plunkett was measuring the amount of gas used by
