PP-reinforced Heterogeneous Cation Exchange Membrane

Catalog Number	ACMA00062976
Description	This is a heterogeneous cation-exchange membrane - PP-reinforced - thickness 450 - 500 µm, with high selectivity and very high mechanical stability. The mechanical reinforcement is composed of polypropylene (also known as PP) and it has the open mesh style.
Application	Electrocoating, electroplating, electrodeionisation, electrodialysis for demineralisation, desalination and others.
Storage	Keep membrane package closed / sealed when unused. Unpack membrane only for direct use and process it immediately after opening. 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	Brown
Delivery Form	Dry
Dimensional Swelling	< 2 %
Hydroxyl Transfer Rate	> 50 nmol min^-1 cm^-2
Ionic Form	Sodium (Na+)
Notice For Use	The membrane is delivered in Na+ 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 T = 25 °C for 24 hrs) to remove any additive from the membrane. Do not let the membrane dry out since micro-cracks may likely occur during shrinkage.
