DuPont AmberLite™ HPR4200 Cl: Reliable Ion Exchange Resin for Versatile Water Treatment Configurations DuPont AmberLite™ HPR4200 Cl sets the standard for versatility and durability in industrial ion exchange applications. Crafted with a styrene-divinylbenzene gel matrix and trimethylammonium functional groups, this chloride-form resin boasts a minimum total exchange capacity of 1.30 eq/L (Cl⁻ form) and a water retention capacity of 49.0–55.0%, ensuring consistent and long-lasting performance. Its yellow, translucent spherical beads feature a uniform particle diameter of 650 ± 50 µm and a uniformity coefficient of ≤1.25, promoting stable hydraulic characteristics and easy backwash separation—especially in mixed bed systems, where its light color enables clear visual distinction from dark-colored cation resins. Designed for seamless pairing with AmberLite™ HPR9500 or HPR9600 resins in single or layered bed systems, it delivers consistent results across co-current, counter-current, and packed bed configurations, supported by DuPont’s 80+ years of expertise in water treatment innovation .
