Summary

Product identification

• Product Name: AmberTec™ UP650 H Ion Exchange Resin
• Type: Uniform Particle Size, Gel, Strong Acid Cation Exchange Resin
• Applications: Single Bed and Mixed Bed Demineralization for the Semiconductor Industry
• Historical Reference: Previously sold as DOWEX™ MONOSPHERE™ 650C UPW (H) Ion Exchange Resin

Description

AmberTec™ UP650 H Ion Exchange Resin is a high-capacity, uniform particle size strong acid cation resin designed for regenerable mixed beds requiring high resin purity and water quality. It offers excellent mechanical strength and cleanness, suitable for high flow rates in mixed bed systems. Its uniform bead size and dark color complement AmberTec™ UP550 OH Ion Exchange Resin, facilitating easy visual separation in mixed beds.
