설명

일반 설명

Aquivion^® PFSA dispersions are based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) CF₂=CF₂-O-(CF₂)₂-SO₂F industrially produced by Solvay Specialty Polymers. The resulting perfluoropolymer′s functional groups are in their sulfonic acid form, SO₃H.

애플리케이션

Aquivion^® D79-25BS can be used as a formulation additive for production of polymer electrolyte fuel cell electrodes, manufacture or repair of cation-exchange membranes, surface coatings of PTFE membranes to improve their wetting behavior or for the development of superacid catalysts. Addition of further film-forming and/or other volatile or non-volatile chemicals is necessary to impart the desired processing and end-product characteristics.
