Nafion™ Membrane Variety Kit

Our Nafion™ Membrane Variety Kits consist of one piece of each of the following Nafion™ membranes:

• Nafion™ 211
• Nafion™ 212
• Nafion™ 115
• Nafion™ 117

Chemours' (formerly DuPont) Nafion™ membranes are non-reinforced films based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form. The physical properties remain the same for the chemically stabilized membranes, which exhibit substantially lower fluoride ion release compared to the non-stabilized polymer – a sign of improved chemical durability. Nafion™ PFSA membranes are widely used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzers. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells that require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable.
