PFSA Dispersion 25%, Water Based

Catalog Number	ACMA00063006
Description	The dispersion's ion-conducting polymer material content is 25% PFSA polymer and the balance is a water-based solvent system. The resin material of this product is based on short side chain PFSA. 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 catalyst ink preparation for PEM fuel cells and PEM electrolyzers in MEA/CCM or electrode production processes, solution casting, solvent casting through the fabrication of PFSA membranes , tape casting, and the generation of ionically conductive media in several other applications such as chemical and electrochemical sensors.
