Food-grade, Reduced Fines, Styrenic, Macroporous, Strong Base Anion Exchange Resin for Cane Sugar Decolorization

AmberLite FPA90RF Cl Ion Exchange Resin has been specially designed for the decolorization of liquid sugar syrups. Ion exchange based decolorization technology has been used more effectively and economically than carbon or bone char based technologies. Sugar refiners and soft drink bottlers around the world have installed AmberLite FPA90RF Cl to successfully decolorize sucrose solutions.

AmberLite FPA90RF Cl is a styrenic, macroporous, Type I strong base anion resin. It is an excellent choice for cane sugar decolorization, offering advantages such as:
– Maximum decolorization efficiency due to the macroporous structure
– Particle size distribution specifically selected to give optimal performance in packed bed and up-flow floating bed systems
– Exceptional physical stability, excellent resistance to osmotic shock, and very good organic fouling resistance

AmberLite FPA90RF Cl reduced fines resin is often used in conjunction with AmberLite 14i Inert Resin, which floats and prevents resin fines from entering the distribution system.

Styrenic AmberLite FPA90RF Cl can be used as a single component or following acrylic AmberLite FPA98 Cl Ion Exchange Resin for highly-colored feed solutions.
