Uniform Particle Size, Gel, Strong Base Anion Exchange Resin for Single Bed and Mixed Bed Demineralization Applications for the Semiconductor Industry.

AmberTec UP550 OH Ion Exchange Resin is a premium quality, high-capacity, uniform particle size resin designed specifically for use in regenerable mixed beds when highest resin purity and water quality are required.
This resin provides exceptional bead integrity and rapid exchange kinetics due to its small average particle size, making it ideally suited to the high flowrate demands commonly encountered in mixed bed systems. The bead size uniformity and a distinguishable light color is tailored to
complement the larger, denser, cationic, gel AmberTec UP650 H Ion Exchange Resin. The color distinction between this pair of resins allows easy visual confirmation of separation following backwash. Together, these resins offer exceptional separation in mixed beds, which combined with excellent water quality and resin purity, has made them known throughout the semiconductor industry as a premium mixed bed pairing.
