PK-reinforced Anion Exchange Membrane,Thickness:75𝜇m

Catalog Number	ACMA00062930
Description	This is a PK-reinforced Anion Exchange Membrane (AEM) with low resistance, high selectivity, high mechanical stability, and high stability in alkaline and acidic environments.
Density	7.0 - 9.0 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	> 2 bar (Test in Water)
Color Form	Brown
Delivery Form	Dry
Dimensional Swelling	0 - 2 %
Electrical Conductivity	4.5 - 6.5 (in Cl- form) mS·cm-1
Elongation At Break	10 - 30 %
Ionic Form	Bromide (Br-)
Non-Std Modulus	1200 - 2300 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 form (without pretreatment) or wet form. For optimum performance it is recommended to rinse the membrane in NaCl solution (e.g. 0.5 M NaCl solution at 25°C for 24 hrs) to remove any additive from the membrane. Place the membrane sample between stabilizing meshes / spacers in order to avoid curling. Do not let the membrane dry out since micro-cracks may likely occur during shrinkage.
