AmberTec™ Ion Exchange Resins

DuPont™ AmberTec™ MR-300 UPW H/OH

AmberTec™ MR-300 UPW H/OH Ion Exchange Resin is an ultrapure water-grade, mixed resin recommended as a working or polishing mixed bed to complement 2-bed ion exchange or reverse osmosis systems. It can be used as a regenerable mixed bed since the color difference and particle size difference will allow a visually good separation to achieve optimal regeneration. Very low ionic load to a regenerable mixed bed can occasionally lead to clumping, especially when the mixed bed is operated to a boron or silica break. An improvement in the manufacturing process of the anion component will eliminate cation/anion clumping under normal regeneration conditions.

The ratio of anion to cation in AmberTec™ MR-300 UPW H/OH is volumetrically optimized to achieve maximum removal of boron and silica.

AmberTec™ Ion Exchange Resins

AmberTec™ Ion Exchange Resins with uniform particle size beads provide improved performance over standard-grade resins with Gaussian particle size distribution. They are available in a wide range of chemical compositions and polymer structures and are ideal for use in industrial water demineralization systems including both co-flow and counter-current-flow regenerations systems, AmberPack™ and Upcore™ Packed Bed Systems, and mixed beds.
