{"product_id":"ceercemc450r","title":"Reinforced Cation-Exchange Membrane (NEXIONIC C450R) for Electrodialysis and Electrodeionization, CEERCEMC450R","description":"\u003cp\u003eThe NEXIONIC® C450R is a high-performance, reinforced cation exchange membrane designed for demanding industrial and laboratory applications. It is a \"strong-acid\" type membrane containing sulfonic acid (-SO3^-) functional groups. Unlike thin, non-reinforced membranes, the C450R is specifically engineered for mechanical stability and longevity in systems with high current densities or aggressive physical conditions.\u003c\/p\u003e\n\u003cp\u003eIt is composed of heterogeneous backbone (resin particles in a polymer matrix) and functional group of strong-acid cation (-SO3^-). Due to its reinforcement and thickness, the C450R is preferred for \"heavy-duty\" electrochemical processes: (1) \u003cstrong\u003eElectrodialysis (ED\/EDR)\u003c\/strong\u003e: Used in industrial desalination and wastewater polishing where high hydraulic pressure or frequent cleaning is required. (2) \u003cstrong\u003eElectrodeionization (EDI)\u003c\/strong\u003e: Serving as the cation-selective barrier in ultrapure water production stacks. (3) \u003cstrong\u003eElectrophoretic Painting or Electroplating\u003c\/strong\u003e: Used in automotive and industrial paint baths to maintain bath chemistry by removing unwanted ions. (4) \u003cstrong\u003eFlow Battery Systems\u003c\/strong\u003e: Employed in certain flow batteries or specialized energy storage systems where a robust separator is needed to prevent electrode contact.
