The Xion™ PEM-Dyneon-725-50 (previously known as Xion™ PEM-725-50) is a composite PEM that use the 3M Dyneion™ resin with an equivalent weight of 725. It is stable under acidic and neutral conditions. This membrane can be used in fuel cells, electrolyzers, electrodialysis, redox flow batteries, electrochemical compressors, and a wide variety of other devices. All Xion™ membranes have high selectivity, high chemical resistance, and durability. The Xion™ PEM-725-50 is a reinforced composite ion exchange membrane that provides excellent mechanical strength and stability to a wide variety of ionomer chemistries.
Current lead time to be expected is 1 - 2 weeks to ship.
