Solvay Specialty Polymers Aquivion® D83-06A Tetrafluoroethylene + SFVE (TFE+SFVE)

Aquivion® PFSA dispersions are based on the unique Short Side Chain (SSC) copolymer of Tetrafluoroethylene and a Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F. The PFSA ionomer dispersions contain its acid form (R-SO3H) and are available in various solvent systems, EWs and concentrations.Aquivion® PFSA dispersions can be used for the production of PEM fuel cell electrodes, electrochemical cell electrodes, manufacture or repair of ion exchange membranes, super-acid catalyst production or surface treatment of PTFE membranes to improve wetting behavior.Additional Properties: Density - Internal Method (25°C): 0.875 g/cm³; Equivalent Weight (EW) - Internal Method 810 to 850 g/eq; Flammability - Yes; HSE/Transport Classification - Flammable; Polymer Concentration - TGA 6 %; Solvent System - 20% Water, 40% 1-Propanol , 40 % 2-Propanol; Solvent Water Content - 25 %; Total Acid Capacity - Internal Method 1.17 to 1.23 meq/g; Viscosity - (25°C): 80 to 100 mPa·sInformation provided by Solvay Specialty Polymers.
