PFSA Dispersion 20%, Alcohol based

Catalog Number	ACMA00063005
Description	The dispersion's ion-conducting polymer material content is 20% PFSA polymer and the balance is a water/alcohol-based solvent system. The PFSA resin used to make this dispersion or ionomer solution is made from the acid (H⁺) form of a chemically stable perfluorosulfonic acid (PFSA)/polytetrafluoroethylene (PTFE) copolymer. Chemical stabilization is also called end group stabilization.
Application	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.
