Gaussian, Acrylic, Gel, Strong Base Anion Exchange Resin for Industrial Demineralization Applications

AmberLite IRA458 Cl Ion Exchange Resin is a general purpose demineralization resin with a long-established track record of reliable performance in the industry. It offers a good balance of high capacity and high strength for co-flow regenerated systems in industrial water treatment.
Acrylic anion resins have a hydrophilic structure providing unique chemical and physical properties allowing for easy release of the accumulated natural organic compounds during the regeneration step. The properties of the acrylic structure also enable it to withstand high osmotic or mechanical stress. The resin has been optimized to yield excellent operating capacity and efficient regeneration. Acrylic resins can be used effectively when temperatures do not consistently exceed 35°C (95°F).
Compared to a Type I styrenic strong base anion resin, AmberLite IRA458 Cl will yield greater operating capacity due to more complete regeneration and exhibits higher organic fouling resistance.
