XION™ Composite Bipolar Membranes are ultra-strong, ultra-selective, and provide ultra-high performance, while demonstrating high chemical stability as reinforced bipolar membranes (BPM). Xergy has the largest selection of cation exchange ionomers (CEI) and anion exchange ionomers (AEI) to select from for BPM design. CEIs available include Dyneon™, Aquivion™, and Nafion™ PFSA ionomers, and AEIs available include Durion™ and Pention™ ionomers. A reinforcement layer is integrated into the structure of the membrane to provide enhanced mechanical properties and reduced swelling. Custom membrane architectures and thicknesses are available upon request.
