Aquivion(R) PFSA ionomer membranes are melt-extruded films based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-(CF2)2-SO2F industrially produced by Solvay Specialty Polymers. Following a film hydrolysis the perfluoropolymer's functional groups are operative in their sulfonic acid form, SO3H.
Synonyms: Aquivion(R) SO3H; Tetrafluoroethylene-perfluoro(3-oxa-4-pentenesulfonic acid) copolymer, Ethanesulfonic acid
Linear Structural Formula: [CF2CF(OCF2CF2SO3H)]m[CF2CF2]n
Application: Aquivion(R) PFSA membranes are used for electrochemical applications such as, but not limited to, polymer electrolyte fuel cells, electro-deionization systems, ozone generators, water electrolyzers, hydrogen separators and compressors, redox flow batteries as well as pervaporation or gas humidification systems.
Legal Information: Aquivion is a registered trademark of Solvay Group
Other Notes: Membranes are packed and sealed in a barrier protection pouch inside a cardboard box to prevent damage or deterioration. It is recommendable storing the product in a clean, humidity-controlled environment protected from direct sunlight or other sources of irradiation or heat. Sheet dimensions are based on product conditioned at 23C and about 50% relative humidity. They may slightly vary upon exposure to different ambient conditions. Maximum temperature rating is 230C, overheating will result in polymer degradation, discoloration and release of toxic volatile decomposition products.
