Unlike the perfluorinated \"F-10\" series (which compete with Nafion), these grades are designed for electrodialysis (ED), diffusion dialysis (DD), and bipolar membrane (BPM) stacks. The primary difference between these grades is their selectivity (which ions they allow through) and their blocking capability (which ions they stop).\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eFKB series (eg: FKB-PK-130)\u003c\/strong\u003e is a specialized cation membrane with high proton conductivity but extremely high resistance to hydroxide (OH-) crossover and its main application is Bipolar Electrodialysis (EDBM).

Its primary application is acid recovery. It has a very high permeability for protons (H+) but a very low permeability for metal cations (like Fe2+, Zn2+, or Cu2+).

While the FAA series is the general-purpose choice for electrolysis and fuel cells, the FAB series is engineered with a proprietary \"low proton crossover\" chemistry. This makes it the preferred choice for applications where you need to block protons (H+) from leaking across the membrane, such as in the production of highly concentrated acids.\u003c\/p\u003e\n\u003cp\u003eThe primary applications of the FAB-PK series membranes are: (1) \u003cstrong\u003eAcid\/Base Production (EDBM): \u003c\/strong\u003eIn a Bipolar Membrane Electrodialysis stack, the FAB membrane is used as the anion-selective layer. Its unique chemistry prevents protons generated at the bipolar interface from migrating into the salt chamber. This allows for the production of much higher concentrations of acid (e.g., HCl or H2SO4) than standard anion membranes. (2) \u003cstrong\u003eAcid Concentration and Recovery\u003c\/strong\u003e: The FAB series is highly effective in processes designed to concentrate acidic solutions. Because of its high proton-blocking capability, it ensures that the acid remains on one side of the membrane while other ions are transported. (3) \u003cstrong\u003eNon-Aqueous Redox Flow Batteries\u003c\/strong\u003e: Due to the stable polyaromatic backbone and PEEK reinforcement, the FAB-PK-130 is often cited as a candidate for organic redox flow batteries using solvents like acetonitrile. The reinforcement prevents the membrane from excessive swelling or \"gelation\" when exposed to organic electrolytes.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 192.637px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.2375px;\"\u003e\n\u003ctd style=\"width: 34.6997%;

This makes them the industry standard for acid recovery from waste streams.\u003c\/p\u003e\n\u003cp\u003eThe FAD membranes are used to recover \"free\" acid from spent pickling or etching liquors in the metal finishing, semiconductor, and mining industries. In a diffusion dialysis stack, the waste acid solution flows on one side of the membrane and water flows on the other. Because of the concentration gradient, the acid (H+ and the anion) diffuses through the membrane into the water. he membrane’s fixed positive charges (quaternary ammonium) allow anions to pass easily. Protons (H+) can tunnel through as well. However, multi-charged metal cations (like Fe3+ or Ni2+) are strongly repelled by the membrane and stay in the waste stream. FAD membranes typically recover 80–90% of the free acid while rejecting 90–95% of the metal contaminants.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 192.637px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.2375px;\"\u003e\n\u003ctd style=\"width: 34.6997%;

Unlike the FAA series, which is optimized for alkaline electrolysis and fuel cells, the FAS series is the industry standard for standard electrodialysis (ED) and water desalination. These membranes are characterized by high permselectivity and a robust polyaromatic backbone that offers excellent stability in neutral to slightly alkaline or acidic solutions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAS-30 and FAS-50 (Non-Reinforced)\u003c\/strong\u003e: These are homogeneous polymer films without an internal fabric mesh. They offer the lowest electrical resistance because 100% of the cross-section is active ion-exchange material, which makes them ideal for high-precision laboratory experiments.
