{"product_id":"ccdcarpcem","title":"Perfluorinated Cation-Exchange Membrane (CEM) for Chlorine Dioxide and Chlorine Alkali Reactor, CCDCARPCEM","description":"\u003cp\u003ePerfluorinated cation-exchange membranes (CEMs)—such as perfluorosulfonic acid (PFSA) and perfluorocarboxylic acid (PFCA) composite films (widely known under commercial designations like Nafion, Flemion, or equivalent industrial grades)—represent the gold-standard separator technology for severe industrial electrochemical environments like chlor-alkali cells and electrochemical chlorine dioxide (ClO2) reactors.\u003c\/p\u003e\n\u003cp\u003eHigh-performance perfluorinated membranes engineered for chlor-alkali and aggressive halogen reactors typically utilize sophisticated composite structures: (1) \u003cstrong\u003eReinforced Mechanical Substrate\u003c\/strong\u003e: Many industrial grades incorporate an embedded expanded polytetrafluoroethylene (ePTFE) fibril mesh reinforcement to eliminate membrane stretching, creep, and dimensional deformation under high differential pressures and fluid velocity. (2) \u003cstrong\u003eAnode-Facing PFSA Layer\u003c\/strong\u003e: A thicker primary layer featuring sulfonic acid groups, optimized for high ionic conductivity, low voltage drop, and stable operation in acidic-to-neutral, chlorine-saturated brine feeds. (3) \u003cstrong\u003eCathode-Facing PFCA Layer\u003c\/strong\u003e: A thin surface layer featuring carboxylic acid groups facing the high-concentration caustic compartment. Carboxylic groups exhibit a much higher electrostatic repulsion barrier against migrating hydroxyl (OH-) ions, preventing back-migration and enabling direct production of high-purity caustic soda (typically 32% to 35% NaOH).\u003c\/p\u003e\n\u003ctable style=\"width: 100.071%; height: 288.4px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCDCARPCEM (C-CDCAR-PCEM)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIt is a good substitution for Dupont N324 membrane. \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eMembrane Thickness (Dry)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e~360 um\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eAcid Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1.0±0.05 meq\/g\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 39.2px;\"\u003e\u003cem\u003eElectrical Conductivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 39.2px;\"\u003e\n\u003cp\u003e≥ 0.1 S\/cm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eWater Uptake\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e~50%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eOperation Temperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026lt;110°C\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.767%;\"\u003e\u003cem\u003eElongation Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%;\"\u003e\n\u003cp\u003e≥ 40 MPa\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eElongation at Break\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e100%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.767%;\"\u003e\u003cem\u003eThickness Swelling Rate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;10%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eL10-40cm*W10-40cm\/pcs\/pack\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eReference: \u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0167273822001333\"\u003eH.
