Fumasep FAP-375-PP is a Fluorinated PP reinforced Anion Exchange Membrane (AEM) with low resistance, high selectivity, high mechanical stability, low dimensional swelling, high oxidative stability, resistant to chlorine and high stability in acidic environment.

Fumasep FAP-375-PP membrane comes in a 10cm x 10cm size sheet. The membrane is the transparent, slightly opaque foil, delivered on a backing layer (colourless rigid PET foil). Pull off carefully the membrane from the backing foil. The membrane is ready for use.

Operation range: Acidic environment pH < 4, at pH > 4 the material has low ionic conductivity. The material is not stable in caustic environment (pH > 10).

Fumatech membranes are highly sensitive to differences in humidity and moisture content. Therefore the membranes can vary +/- 0.5cm from the original cut sizes. Also due to this sensitivity the manufacturer expects wrinkles to form, however soaking the membranes in deionized water will return the membranes to the full size planar state according to the manufacturer.

Fumasep FAP-375-PP Features:

 • Applications: Electrochemical processes requiring anion exchange membranes with high oxidative stability and highly resistant to chlorine.
 • Anion Exchange Membrane (AEM)
 • Thickness: 70 - 80 micrometers (2.76 - 3.15 mil)
 • Sizes: 10cm x 10cm

Fumasep FAP-375-PP Technical Specification Sheet


Keep membrane package closed / sealed when unused. Store, handle and process the membrane in a clean and dust-free area. Use only new and sharp knives or blades, when cutting the membrane. Always wear protective gloves when handling the membrane. Handle with care, be sure not to puncture, crease or scratch the membrane, otherwise leaks will occur. All surfaces in contact with the membrane during handling, inspection, storage and mounting must be smooth and free of sharp projections.

Pre-Treatment and Conditioning:

The membrane is delivered in dry form. The membrane does not need any pretreatment and is ready for use. Please assemble the membrane in dry form.

If you have any concerns about storage, chemical stability, pre-treatment or before proceeding, please feel free to contact us for further information.

Long Term Storage:

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.

Please note that a current lead time of one to two weeks is to be expected.
