Nafion (copolymer made from PTFE and perflourinated Monomer)

Nafion (copolymer made from PTFE and perflourinated Monomer)Description:

Nafion is a copolymer of tetrafluoroethylene (Teflon) and perfluoro-3,6-dioxa-4-methyl-7-octene-sulfonic acid. Like Teflon, Nafion is highly resistant to chemical attack, but the presence of its exposed sulfonic acid groups confers unusual properties. Sulfonic acid has a very high water-of-hydration, absorbing 13 molecules of water for every sulfonic acid group in the polymer. Consequently, Nafion absorbs 22% by weight of water.


  • as membrane:
    • chlorine alkali elektrolysis
    • fuel cells
  • as membrane/tube: gas drying
  • as pellets: acid catalyst for organic synthesis
  • in solution: raw material for polymer synthesis
