PK-reinforced Anion Exchange Membrane,Thickness:130𝜇m,TotalExchangeCapacity:1.1-1.4 meq/g

Catalog Number	ACMA00062929
Description	This is a PK reinforced Anion Exchange Membrane (AEM) with low resistance, high selectivity, very high mechanical stability, and high stability in acidic and caustic environment.
Density	10 - 13 mg·cm-2
Application	Electrodialysis for demineralization, desalination, capacitive deionization and others. This membrane can also be used for standard alkaline fuel cell and electrolyzer applications that utilize slightly alkaline solutions (1-2 Molar).
Storage	Dry Form: 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. Wet Form: Storage for short and medium time scale (hours up to several weeks) may be done in unsealed containers in 0.5 - 1.5 wt% NaCl solution or comparable neutral pH electrolytes.
Backing Foil	None
Bubble Point	> 3 bar (Test in Water)
Color Form	Brown
Delivery Form	Dry
Dimensional Swelling	0 - 2 %
Electrical Conductivity	4.0 - 8.0 (in Cl- form) mS·cm-1
Elongation At Break	15 - 40 %
Ionic Form	Bromide (Br-)
Non-Std Modulus	1000 - 1800 MPa
Notice For Use	The membrane is delivered in bromide form and dry form. Depending on application and cell design, assembling is possible in dry (without pretreatment) or wet form. Before assembling in wet form put the membrane sample between stabilizing meshes / spacers (in order to avoid curling) in NaCl solution - e.g. 0.5 M NaCl solution at 25°C for 72 hours exchanging the solution several times. Do not let the membrane dry out since micro-cracks may likely occur during shrinkage.
