产品说明
一般描述
Aquivion® 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.
应用
Aquivion® 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.
其他说明
Handling:
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 23 ℃ and about 50 % relative humidity. They may slightly vary upon exposure to different ambient conditions. Maximum temperature rating is 230℃, overheating will result in polymer degradation, discoloration and release of toxic volatile decomposition products.
