DuPont™ AmberLite™ IRA402 Cl Strong Base Anion Exchange Resin – Industrial Demineralization
DuPont™ AmberLite™ IRA402 Cl is a Gaussian, gel-type, strong base anion exchange resin (Type I) with a long-established track record of reliable performance in industrial demineralization applications. This industry-staple resin provides an excellent balance of properties including high capacity, physical strength, silica selectivity, and long service life. It is particularly well-suited for co-current flow regenerated systems treating water with high percentages of silica, delivering efficient removal of strong and weak acids with minimal silica leakage.
