AMBERLITE™ IRA458RF Cl Resin

Industrial Grade Strong Base Anion Exchanger

Description

    AMBERLITE IRA458RF Cl Resin is an acrylic gel type strong base anion exchange resin, with distinct chemical and physical properties. It combines high operating capacity with low silica leakage values. The flexible acrylic structure of AMBERLITE IRA458RF Cl Resin allows for effective adsorption and desorption of naturally occurring organic molecules, such as humic and fulvic acids, that are present in many water supplies. The particle size distribution of AMBERLITE IRA458RF Cl Resin has been specially selected to give optimum performance in floating bed and packed bed applications.
