About Nafion R-1000 Precursor Beads
Brand: Chemours
Product Code: 72500302
Chemours (formerlyDuPont) Resins are perfluorinated polymers used to manufacture ion-exchangemembranes, catalysts, and related materials. It is a copolymer of tetrafluoroethyleneand perfluoro-3,6-dioxa-4-methyl-7-octenesulfonyl fluoride. This thermoplasticpolymer must be hydrolyzed to convert it to a form suitable for use inion-exchange applications.
