Who first discovered Teflon microporous membrane?

About 70 years ago, chemist Dr. Roy J. Plunkett invented polytetrafluoroethylene resin in DuPont’s Jackson Laboratory in New Jersey, USA. DuPont used “Teflon” as the brand name of the product.

Subsequently, DuPont developed a series of products in addition to Teflon polytetrafluoroethylene resin, including TeflonAF (amorphous fluoropolymer), Teflon microporous membrane, TeflonFEP (fluorinated ethylene propylene) Resin), TeflonFFR (fluoropolymer foam resin), TeflonNXT fluoropolymer resin, TeflonPFA (perfluoroalkoxy resin), etc.

PTFE film manufacturer specializes in the production of polytetrafluoroethylene microporous membranes. The product materials produced are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
