Non-reinforced Fluorinated Anion Exchange Membrane

Catalog Number	ACMA00062917
Description	This is a non-reinforced Fluorinated Anion Exchange Membrane (AEM) with low resistance, high blocking capability of vanadium ions, and high stability in acidic environment. The polymer backbone for this AEM is based on a hydrocarbon polymer material.
Density	7.5 - 8.5 mg·cm-2
Application	Redox-Flow Battery, e.g. Vanadium-Redox-Flow Battery (VRB), using aqueous acidic conditions.
Storage	The membrane can be stored dry for an unlimited amount of time. However, the membrane has to be conditioned (washed and rinsed) prior to use.
Backing Foil	Between Paper
Bubble Point	> 4 bar (Test in Water)
