{"product_id":"ceefcaemfas","title":"Anion-Exchange Membrane (Fumasep, FAS Series) for Electrodialysis, Electrolyzer and Fuel Cell, CEEFCAEMFAS","description":"\u003cp\u003eThe Fumasep FAS series is a family of hydrocarbon-based anion exchange membranes (AEMs) produced by Fumatech BWT. 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. However, they are mechanically delicate and can \"wrinkle\" or swell significantly if not hydrated properly before assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAS-PET-75 and FAS-PET-130 (PET Reinforced)\u003c\/strong\u003e: These membranes feature an internal woven Polyethylene Terephthalate (PET) mesh that acts as a skeleton. In large-scale industrial stacks (which can be over 1 meter in height), non-reinforced membranes would sag or stretch under the weight and flow of the water. The PET reinforcement ensures the membrane stays flat and maintains its dimensions. These membranes are significantly more resistant to tearing during the manual assembly and tightening of a plate-and-frame stack.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 18%;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 20%;\"\u003e\n\u003cp\u003eCEEFCAEMFAS30\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 20.5995%;\"\u003e\n\u003cp\u003eCEEFCAEMFAS50\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.4005%;\"\u003e\n\u003cp\u003eCEEFCAEMFASPET75\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eCEEFCAEMFASPET130\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 18%;\"\u003e\u003cem\u003eMembrane Name\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 20%;\"\u003e\n\u003cp\u003eFAS-30\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 20.5995%;\"\u003e\n\u003cp\u003eFAS-50\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.4005%;\"\u003e\n\u003cp\u003eFAS-PET-75\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eFAS-PET-130\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 18%;\"\u003e\u003cem\u003eThickness (um)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 20%;\"\u003e\n\u003cp\u003e~30 um (25-35 um range)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 20.5995%;\"\u003e\n\u003cp\u003e~50 um (45-55 um range)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.4005%;\"\u003e\n\u003cp\u003e~75 um (70-80 um range)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003e~130 um (110-130 um range)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 18%;\"\u003e\u003cem\u003eReinforcement\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 20%;\"\u003e\n\u003cp\u003eNone (Self-Supporting)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 20.5995%;\"\u003e\n\u003cp\u003eNone (Self-Supporting)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.4005%;\"\u003e\n\u003cp\u003eYes (PET Mesh)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eYes (PET Mesh)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 18%;\"\u003e\u003cem\u003eBacking Foil\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 20%;\"\u003e\n\u003cp\u003eYes (PET)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 20.5995%;\"\u003e\n\u003cp\u003eYes (PET)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.4005%;\"\u003e\n\u003cp\u003eNone\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eNone\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 18%;\"\u003e\u003cem\u003eCounter Ion\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 20%;\"\u003e\n\u003cp\u003eBr-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 20.5995%;\"\u003e\n\u003cp\u003eBr-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.4005%;\"\u003e\n\u003cp\u003eBr-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003eBr-\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 18%;\"\u003e\u003cem\u003eSpecific Area Resistance (in Cl- form, Ω•cm2)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 20%;\"\u003e\n\u003cp\u003e0.3-0.6\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 20.5995%;\"\u003e\n\u003cp\u003e0.6-1.5)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 19.4005%;\"\u003e\n\u003cp\u003e1.2-2.0\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 17%;\"\u003e\n\u003cp\u003e1.7 -
