Syensqo (Solvay Specialty Polymers) Aquivion® D79-25BS Perfluorosulfonic Acid (PFSA) Ionomer Dispersion (Unverified Data**)
Categories:	Polymer
Material Notes:	Aquivion® D79-25BS is a chemically-stabilized (denoted by S-suffix) perfluorosulfonic acid (PFSA) ionomer dispersion that exhibits an Equivalent Weight (EW) of 790 g/eq. Polymer concentration is 25%. Solvent system is >99% water and is free of ethers. Aquivion® PFSA dispersions are based on the Short Side Chain copolymer of Tetrafluoroethylene (TFE) and Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F. The PFSA ionomer dispersions contain its acid form (-SO3H) and are available in various solvent systems, EWs and concentrations. These dispersions can be used to produce PEM fuel cell electrodes and electrochemical cell electrodes, to manufacture or repair ion exchange membranes, to produce super-acid catalysts, and for the surface treatment of PTFE membranes to improve wetting behavior. Availability: Asia Pacific; Europe; North America Information provided by Solvay Specialty Polymers.
