Perfluorosulfonic Acid Resin HNF-5W

HNF-5W is a perfluorosulfonic acid ion exchange resin jointly developed by our company and famous domestic scientific research institutions for solid super acid catalytic applications. Perfluorosulfonic acid resins currently produced by DuPont and others are mainly produced as raw materials for the production of membrane materials with ion exchange functions in the ion membrane caustic soda industry. Generally, perfluorovinyl ether monomers with sulfonic acid groups are copolymerized with tetrafluoroethylene to obtain perfluorosulfonic acid resin Nafion-H. Although it is very acidic, its acidity is difficult to fully exert. In response to this situation, our company has researched and developed a special production process to allow more hydrogen ions to fully contact the materials during the chemical reaction, thus significantly improving the catalytic activity.
