AMBERLITE™ Ion Exchange Resins and Polymeric Adsorbents are available in a very wide range of chemical compositions and polymer structures and have been used for decades in a high-value applications including water treatment in industrial and power generation plants, drinking water, food processing, chemical processing, bioprocessing, and pharmaceutical formulations.
AMBERLITE™ FPA54 Ion Exchange Resin is a macroporous, weak base anion resin. This unique, highly porous resin is based on a crosslinked phenol-formaldehyde matrix. The low swelling characteristics of AMBERLITE FPA54 resin give it excellent osmotic and physical stability resulting in less product loss and longer product life than conventional styrenic resins. The combination of the unique porous matrix and the hydrophilic phenolic structure of AMBERLITE FPA54 permit the reversible adsorption of high molecular weight organic color bodies frequently found in solutions of natural products and fermentation products. AMBERLITE FPA54 resin exhibits a high selectivity for sulfates and phosphates, making it ideal for the treatment of both citric and lactic acids derived from fermentation where it has a long history of use, particularly due to its excellent osmotic stability. It can be more effective than conventional polystyrene resins in this and other food product applications.
