Perfluorinated PK-reinforced Cation Exchange Membrane

Catalog Number	ACMA00062964
Description	This is a Perfluorinated PK-reinforced Cation Exchange Membrane (CEM) with low resistance, high mechanical stability, high selectivity, and high chemical and oxidative stability. The polymer composition of this membrane is based on the perfluoro sulfonic acid resin with long side chains. The mechanical reinforcement is composed of PEEK or PK and it has an open mesh style.
Density	13 - 14 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.
