Xion ™ PEM-Nafion-1000-05 Membrane - AO-72600082

The Xion™ Composite PEM-Nafion-1000-05 is a reinforced composite ion exchange membrane that provides excellent mechanical strength and stability to a wide variety of ionomer chemistries.  The mechanical reinforcement is the microporous expanded PTFE matrix, which has excellent thermal, chemical, and mechanical stability under various conditions.

All Xion™ membranes have high selectivity, high chemical resistance, and durability. Image on the right side shows the chemical composition of the Nafion resin.

The XION Composite NAFION Membranes are ultra-thin, highly conductive, and highly stable reinforced proton exchange membranes (PEM). The membranes are based on a perfluorosulfonic acid (PFSA) ionomer developed by Chemours. NAFION has been manufactured for over 40 years and is the most robust PFSA ionomer on the market with the long side chain and durable end group capping.
A reinforcement layer is integrated into the structure of the membrane to provide enhanced mechanical properties.
The enhanced mechanical properties allow Ultra-thin, Ultra-Strong, and Ultra-High-Performance free-standing membranes, i.e. providing higher ionic conductivity without sacrificing strength. Applications for XION Composite NAFION Membranes include fuel cells, electrolyzers, and sensors. XION Composite NAFION Membranes are available in two variations based on the equivalent weight (EW) of the ionomer. 1000EW has slightly higher ionic conductivity, but 1100EW has slightly greater stability.
