Nafion™ Resins for Ion Exchange Membranes

Use of Nafion™ Polymers in Pellet Form

The same polymers used to make Nafion™ membranes and dispersions are also available as ready-to-use pellets chemically converted to the proton form.

Nafion™ Superacid Resins

Nafion™ resins considered to be superacids (acidity greater than 100% pure sulfuric acid) can be used as catalysts for organic synthesis in numerous applications, including:

  • Alkylation
  • Oxidation
  • Isomerization
  • Oligomerization
  • Acylation
  • Ketalization
  • Esterification
  • Hydrolysis of sugars and ethers

Better conversion occurs when a superacid catalyst is used, because it reduces catalyst usage and increases reaction rates. 

Multiple grades are available with different ion exchange capacities and sizes (see Table). Please consult with the technical service team for Nafion™ products for further information.
