Felite^™ FMB401-B is the mixture of Felite^™ FC108-MHB (Mono Polymerized, hydrogen form strong acid cation resin, black color) and Felite^™ FA127-MOH (Mono Polymerized, hydroxide form type I strong base anion resin) with the ratio 2:3.

Felite^™ FMB401-B is designed to produce very high water quality and to separate easily for regeneration. It is intended to use in all mixed bed deionization applications that require high resistivity and high capacity.

Felite^™ FMB401-B is particularly well suited for portable exchange and other polishing applications. It’s supplied ready to use form, and the resistivity can reach up to 10+ megohms.
