Non-reinforced Cation Exchange Membrane,Thickness:50𝜇m,TotalExchangeCapacity:1.2-1.4 meq/g

Catalog Number	ACMA00062954
Description	This product is a non-reinforced Cation Exchange Membrane (CEM) with very low resistance, high selectivity and high stability in pH acidic and basic environments.
Density	7.5 - 8.3 mg·cm-2
Application	Designed for Electrodialysis for demineralisation, desalination, capacitive deionization and others.
Storage	Dry form: Membranes can be stored dry for an unlimited period of time. However, the membrane must be conditioned (washed and rinsed) before use. Wet form: Available for short- and medium-term storage (hours to weeks) in unsealed containers in 0.5 - 1.5 wt% NaCl solution or similar neutral pH electrolyte.
Backing Foil	PET Foil
Bubble Point	> 2.5 bar (Test in Water)
Color Form	Transparent / Brown
Delivery Form	Dry (non-activated)
Dimensional Swelling	0 - 2 %
Electrical Conductivity	2.0 - 3.0 (in Na+ form) mS·cm-1
Ionic Form	H-form
Notice For Use	Membranes are delivered in H and dry versions. Depending on the application and cell design, assembly can be done in dry (without pretreatment) or wet form. For optimal performance, it is recommended to rinse the membrane in a NaCl solution (e.g., 0.5 M NaCl solution at 25°C for 24 hours) to remove any additives on the membrane. Place the membrane sample between stabilizing mesh/spacers to avoid curling. Do not let the film dry as micro-cracks may appear during shrinkage.
