Generic F-10120 F-10120-PK is a Non-Reinforced Cation Exchange Membrane (F-10120_20CM*20CM)

1. F-10120 F-10120-PK Cation Exchange Membrane: (1) Introduction: F-10120, F-10120-PK is a non-reinforced Cation Exchange Membrane (CEM) with low resistance, high mechanical stability, high selectivity and high chemical / oxidative stability, and resistant to chlorine. The perfluorinated sulfonic acid (PFSA) membrane's functional sites are based on long side chain (LSC) composition. (2) Delivery: The membrane is the colourless, transparent foil, delivered on a backing foil (colourless rigid PET foil). Pull off carefully the membrane from the backing foil. The standard size of this membrane is 10*10cm & 20*30cm. Customized dimensions can be made upon request. (3) Precautions: 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. (4) Features: - Applications: Electrochemical processes requiring cation exchange membranes with high oxidative stability and highly resistant to chlorine (e.g. for electrode protection). - Cation Exchange Membrane (CEM) - Thickness: 120 micrometers (μm) If you have any concerns about storage, chemical stability, pre-treatment or before proceeding, please feel free to contact us for further information.

• 1. F-10120 Cation Exchange Membrane:(1) Welcome to cite our materials in your papers: F-10120, a non-reinforced Cation Exchange Membrane (CEM), was obtained from SCI Materials Hub.
• (2) Handling: Keep membrane package closed / sealed when unused. Unpack membrane only for direct use and process immediately after opening. Store, handle and process the membrane in a clean and dust-free area. 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 which may get into contact with the membrane during inspection, storage, pretreatment and mounting must be free of sharp edges or angles.
• (3) Storage: Dry Form: 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. 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. For storage over a longer time period a sealed container is recommended using afore said electrolyte with ca. 100 ppm biocide (NaN3) to avoid biological fouling.
• (4) Pre-Treatment and Conditioning: The membrane is delivered in H-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 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.

• (2) Handling: 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. Membranes will expand and contract based on water / electrolyte content.
• (3) 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.
• (4) Pre-Treatment and Conditioning: The membrane is delivered in H-form and dry form (non-activated). For optimum performance and lowest resistance it is necessary to pretreat the membrane according to the following prescription: Put the membrane sample in an aqueous 10 wt% HNO3 solution or in 5 vol % H2SO4 solution at minimum 80°C for at least 12 hours. After rinsing with demineralized water (pH ~ 7) the membrane is ready for use (activated). Membranes will expand and contract based on moisture content.
