DuPont Ion Exchange Resin
DuPont Ion Exchange Resins, in the AmberLite™ and AmberSep™ portfolios, are high-performance synthetic resins for advanced water treatment, including demineralization, softening, specialty separations, and industrial process control.

DuPont Ion Exchange Resins, part of the AmberLite™ and AmberSep™ portfolios, are high-performance synthetic resins designed for advanced water treatment applications—from demineralization and softening to specialty separations and industrial process control.
Core Advantages
-
High exchange capacity and mechanical stability, featuring uniformly cross-linked polystyrene-divinylbenzene beads.
-
Specialized formulations: strong acid cation (SAC), strong base anion (SBA) Types I & II, weak base anion (WBA), chelating resins, and macroporous organics adsorbents.
-
Robust chemical tolerance, including resistance to oxidants, temperature, and pH, supporting rigorous regeneration cycles.
Featured Resins
-
AmberLite™ IR69F (SAC): Pharmaceutical-grade strong acid cation resin, >4.4 eq/kg total exchange capacity, ideal for drug-delivery and high-purity water systems.
-
AmberLite™ HPR1210 H (SAC): Uniform particle size, optimized for industrial demineralization and mixed-bed polishing, reducing chemical and rinse-water usage.
-
AmberLite™ FPA52RF (WBA): Weak base anion resin with macroporous structure, excellent for organic removal in food, beverage, and industrial applications.
