AMBERLITE™ Ion Exchange Resins

AMBERLITE™ Ion Exchange Resins are available in a very wide range of chemical compositions and polymer structures and have been used for decades in a high-value applications including water treatment in industrial and power generation plants.


AMBERLITE™ IRN77 H Ion Exchange Resin a Nuclear-grade, Uniform Particle Size, Gel, Strong Acid Cation Exchange Resin for Water Treatment Applications in the Nuclear Power Industry. It is designed specifically for use in nuclear loops where highest resin purity and stability are required, and where the "as supplied" resin must have a minimum of ionic and non-ionic contamination. These high standards of resin purity enable plants to achieve reliable and safe production whilst reducing the need for equipment maintenance and minimizing the impact of unscheduled outages. AMBERLITE IRN77 H is a high capacity, 8% DVB cation resin used to remove cations for purification and pH control in primary water treatment. It contains a minimum of 99% of its exchange sites in the hydrogen form. The uniform particle size and the absence of fine resin beads results in a lower pressure drop compared to conventional resins.
