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™ IRN164 Li/OH Ion Exchange Resin is a Mixture of Nuclear-grade, Uniform Particle Size, Gel, Strong Acid Cation and Strong Base Anion Exchange Resins 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 IRN164 Li/OH is composed of AMBERLITE™ IRN97 H Ion Exchange Resin converted to the natural Li form and AMBERLITE™ IRN78 OH Ion Exchange Resin, supplied together on a 1:1 equivalent basis. AMBERLITE IRN164 Li/OH is designed for use in CANDU reactor heat transport systems and closed-loop cooling systems. It is intended for use in non-regenerable systems which demand high effluent purity and long resin life. The properties of this mixed bed resin make it less separable helping to eliminate the formation of a cation layer at the bottom of the service vessel when transferring from one location to another. In addition, the mixed bed is specially processed to have a good slurrying capability. As a pre-mixed resin, it allows for faster change-out and initial rinse-up prior to service, which minimizes start-up time and rinse wastewater volume.
