PFSA Dispersion 5%, Alcohol based

Catalog Number	ACMA00063007
Description	This product is a homogeneous solution based on perfluorosulfonic acid for the preparation of catalyst inks for PEM fuel cells and PEM electrolyzers in MEA/CCM or electrode production processes, manufacturing PFSA membranes by solution casting, solvent casting, tape casting Molding and generation of ionically conductive media in several other applications such as chemical and electrochemical sensors, etc.
Application	The dispersion has an ion-conducting polymer material content of 5% PFSA polymer and the remaining solvent system is water/alcohol based. The PFSA resin used to prepare this dispersion or ionomer solution is made from the chemically stable acid (H⁺) form of perfluorosulfonic acid (PFSA)/polytetrafluoroethylene (PTFE) copolymer. Chemical stabilization is also called end group stabilization.
