PET-enhanced Cation Exchange Membrane

Catalog Number	ACMA00062965
Description	This product is a PET-enhanced cation exchange membrane (CEM) with low resistance, high selectivity, extremely high mechanical stability, and high stability in pH-neutral and acidic environments.
Density	8.5 - 10.5 mg·cm-2
Application	Electrodialysis for demineralisation, desalination, acid recovery applications 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	None
Bubble Point	> 3 bar (Test in Water)
Color Form	White
Delivery Form	Dry
Dimensional Swelling	0 - 1 %
Electrical Conductivity	2.5 - 4.5 (in Na+ form) mS·cm-1
Elongation At Break	20 - 40 %
Hydroxyl Transfer Rate	10 - 30 µmol·min-1·cm-2
Ionic Form	H-form
Non-Std Modulus	1300 - 1900 MPa
Notice For Use	The membrane is delivered in H+ 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.
