D111 Macroporous Weak Acid Cation Exchange Resin
详细说明
1.Description
D111 This is a kind of cation exchange resin which has carboxylic acid groups [-COOH] in the macroporos acrylic acid-divinylbenzene copolymer. It works with large exchange capacity, speedy exchange ability, small volumn change, good physical strength and chemical stability, excellent capabilities of contamination and oxidation resistance etc.
