Weakly Basic Epoxy-based Anion Exchange Resin

PRODUCT DATA SHEET:

KP-resin model #330 is a weakly basic anion exchange resin with a clear gel structure. This resin is based on the cross-linking polycondensation of epoxy chloropropane and polyethylene polyamine, which contains primary amines, secondary amines, tertiary amines and a few quaternary amines as functional groups. With its extra high exchange capacity, high efficiency in elution &regeneration and strong adsorption to organics by its fine-polymerized physical porosity, this resin is primarily used in demineralization and decolorization applications such as antibiotic refining, amino acid separation and lactic acid refining, etc.
