Aquivion(R) E87-05S membrane sheet, contains CF3 polymer chain ends as stabilizer, PFSA eq. wt. 870 g/mole SO3H, L x W x thickness 18 cm x 18 cm x 50 mum

Uses

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.

Uses

• Aquivion^? PW79S acid powder exhibits concentrated ion cation-exchange capacity and can be used under the conditions where conventional exchange resins have shown insufficient chemical resistance.
• Given the resin′s superacid functionality with many active groups it can also be used either directly or as an ingredient of composite structures active as heterogeneous catalysts. This encompasses a wide range of organic synthesis and respective reaction mechanisms, as already described in public literature.

• Given the resin′s superacid functionality it can also be used either directly or as an ingredient of composite structures in the field of heterogeneous catalysis. This encompasses a wide range of organic synthesis and respective reaction mechanisms, as already described in public literature.

General Description

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.
