Application

Nafion™ is a perfluorinated ion-exchange membrane which has a wide variety of commercial uses. The acidic (hydrogen ion) form and derivatives are solid, superacid catalysts useful in a wide variety of synthetic applications.
Nafion™ perfluorinated membrane (Nafion 117) is a composite material that can be used as an electrolytic ion-exchange membrane for the fabrication of fuel cells.

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Packaging

Darkening/browning is common for pieces stored in a general room environment for an extended period of time (several months), due to organics pick-up. Verify product is kept sealed during storage.
  • Keep pieces sealed and protected from general exposure will reduce the effect. Recommend long term storage in air-tight bags.
  • Discoloration does not affect performance and can be removed by soaking in dilute nitric acid.
