High Operating Capacity, Uniform Particle Size, Macroporous, Weak Base Anion Resin for Sweetener Applications

AmberLite FPA77 UPS Ion Exchange Resin is a high operating capacity, uniform particle size, macroporous, weak base anion resin for use in deashing sweeteners to produce low-conductivity syrups.

Premium-grade AmberLite FPA/FPC UPS Resins help decrease operating costs, and help improve plant capacity. These premium resins extend syrup run times up to 25%, reducing downtime and the chemicals spent on regeneration. A simple change to premium AmberLite FPA/FPC UPS resins can postpone or eliminate the need for capital expansion. The uniformity of the beads also reduces sweet water production and rinse requirements after regeneration, possibly reducing wastewater treatment costs.

In addition to the advantages of its uniform particle size and macroporous matrix, the special formulation of AmberLite FPA77 UPS provides the highest operating capacity and, therefore, the lowest processing cost available.

The macroporous matrix also provides excellent mechanical strength.
