Syensqo (Solvay Specialty Polymers) Aquivion® E87-10 Tetrafluoroethylene + SFVE (TFE+SFVE) (discontinued **)
Categories:	Polymer; Thermoplastic; Fluoropolymer
Material Notes:	Aquivion® PFSA ionomer membranes are melt-extruded products based on the unique Short Side Chain (SSC) copolymer of Tetrafluoroethylene and a Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F of low molecular weight produced by Solvay Specialty Polymers. Aquivion® PFSA ionomer membranes are available in the acid form and feature lower Equivalent Weight (EW) than most competitive proton exchange membranes. The SSC copolymer allows higher crystallinity, improved mechanical properties and better proton conductivity. Typical applications of Aquivion® PFSA membranes are PEM fuel cells, water electrolyzers, H2 separators, pervaporation or gas humidification systems. Membrane grades are presently subdivided in two families E87 and E79 which exhibit different EW of 870 or 790 g/eq SO3H. The value is controlled systematically according to an internal titration procedure. Nominal thicknesses are 30 or 50 µm - with E87 also available at 100. Others may be available upon request. For some applications, it can be recommendable to use chemically stabilized membranes (recognizable through their S-suffix). E79 grades are exclusively available in their chemically stabilized form. Additional Information: HEALTH, SAFETY AND ENVIRONMENT - Aquivion® PFSA membranes are not harmful if used and handled according to standard processing procedures (see for example the "Guide to the Safe Handling of Fluoropolymer Resins" issued by the Society of the Plastics Industry). If handled inappropriately, membranes may release harmful toxic chemicals. PACKAGING, SHIPMENT AND STORAGE - The membranes are usually available in sheets of customized formats or rolls in various lengths (dimensions are based on dry product conditioned at 23 °C and 50 % Relative Humidity). They are sealed in an inert environment with a multilayer protection film before packaging inside a shock-protected cardboard box. It is recommended to store the product in a clean, controlled humidity environment and protected from direct sun light or other sources of heat. Information provided by Solvay Specialty Polymers.
