Non-reinforced Anion Exchange Membrane,Thickness:50𝜇m,Tensile Strength 30-40 MPa

Catalog Number	ACMA00062915
Description	This is a non-reinforced Anion Exchange Membrane (AEM) with very low resistance, high selectivity and high stability in pH acidic and basic environments.
Density	6.0 - 8.5 mg·cm-2
Application	Electrodialysis for demineralisation, desalination, capacitive deionization and others. This membrane can also be used for standard akaline fuel cell and electrolyzers that are utilizing 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	PET Foil
Bubble Point	> 2.5 bar (Test in Water)
Color Form	Transparent / Brown
Delivery Form	Dry
Dimensional Swelling	0 - 1 %
Electrical Conductivity	3 - 8 (in Cl- form) mS·cm-1
Elongation At Break	15 - 60 %
Ionic Form	Bromide (Br-)
Non-Std Modulus	1000 - 1800 MPa
Notice For Use	The membrane is delivered in bromide form (Br-) and dry form. For standard alkaline fuel cell / electrolysis applications, the membrane should be converted into OH-form by treating it with 0.5 - 1.0 M NaOH or KOH solution: Put the membrane sample in an aqueous solution of 0.5 - 1.0 M NaOH or KOH for at least 24 h at 20°C - 30°C. After rinsing with demineralised water (pH ~ 7) the membrane is ready to use. Use closed container to avoid CO2 contamination (carbonate formation that may affect conductivity). The membrane in OH-form must be stored under wet / humidified and CO2-free conditions, avoid drying out of the membrane in OH-form. Long-term storage in dry conditions should be preferably done in carbonate, Cl- or Br-form.
