This is a kind of cation exchange resin which has carboxylic acid groups [-COOH] in the acrylic acid-divinylbenzene copolymer. It is produced by using the way of once pore forming with twice polymerizations.This product has good physical and chemical properties,such as large exchange capacity, speedy exchange ability, strong organic contamination resistance, good regenerability, speedy elution, good physical strength, strong capabilities of permeation resistance and so on.
