PP-reinforced Heterogeneous Anion Exchange Membrane

Catalog Number	ACMA00062934
Description	This is a heterogeneous anion-exchange membrane - PP-reinforced - thickness 450 - 500 µm, with high selectivity and very high mechanical stability. The membranes are highly sensitive to differences in humidity and moisture content. Therefore the membranes can vary +/- 0.5cm from the original cut sizes.
Application	Electrocoating, electroplating, electrodeionisation, electrodialysis for demineralisation, desalination and others.
Storage	Dry form: Storage for long time scale (> 12 month) may be done in dry state (sealed container). 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	Light yellow
Dimensional Swelling	< 2 %
Electrical Conductivity	> 1.7 mS cm-1 (Cl- form)
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. Pretreatment before assembling: Put the membrane sample between stabilizing meshes / spacers (in order to avoid curling) in NaCl solution - e.g. 0.5 M NaCl solution at T = 25 °C for 72 hrs exchanging several times the solution. Do not let the membrane dry out since micro-cracks may likely occur during shrinkage.
