AmberLite HPR4100 Cl Ion Exchange Resin is a Uniform Particle Size, Gel, Strong Base Anion (Type II) Exchange Resin for Industrial Demineralization Applications. It is a high-quality resin for use in industrial demineralization applications when a balance of operating performance and simple, cost-effective operation is required. The chemical properties and particle size of the resin have been optimized to help yield excellent operating capacity and rinse characteristics, reducing chemical regenerant and rinse water usage while maintaining a superior physical stability. Compared to a Type I strong base anion resin, a Type II resin will yield greater operating capacity due to more complete regeneration. It is best-suited to treat water in which silica and carbon dioxide do not exceed 30% of the total anions and the service and caustic regeneration temperature does not consistently exceed 35C (95F). For systems that require low silica in the effluent or that operate in higher temperatures, a Type I strong base anion resin is recommended, such as: AmberLite HPR4200 Cl or OH Ion Exchange Resin, AmberLite HPR4800 Cl or OH Ion Exchange Resin
