Non-reinforced Anion Exchange Membrane,Thickness:50𝜇m,Tensile Strength 25-40 MPa

INQUIRY
Catalog Number ACMA00062914
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 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 PET Foil
Color Form Transparent / Brown
Delivery Form Dry
Dimensional Swelling 0 - 2 %
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 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. Membranes will expand and contract based on water / electrolyte content.
