Macroporous, Type II Strong Base Anion Resin for Mixed Bed Sweetener Applications

AmberLite FPA22 Ion Exchange Resins are macroporous, Type II, strong base anion resins for use in mixed bed polishing in sweetener applications to produce syrup products with maximum shelf stability. The macroporous matrix provides excellent mechanical strength and good operating capacity.

AmberLite FPA22 OH Ion Exchange Resin is shipped in the regenerated (OH−) ionic form.

Anionic AmberLite FPA22 OH resin can best be used in a mixed bed polisher together with cationic AmberLite FPC88MB H Ion Exchange Resin. Or, for a pair of resins, each in their most stable form, AmberLite FPA22 Cl is commonly purchased with AmberLite FPC88MB Na Ion Exchange Resin, which is in the Na+ form.
