Advantages

This product is a type of weak alkaline anion exchange resin with polyamine groups which is achieved by aminolysis of methyl acrylate crosslinking copolymer with macroporous structure through ethylene polyamine. It has properties like large exchange capacity, small volume change, high mechanical strength, good chemical stability and excellent resistance of stain and oxidation, fast exchange rate and others.

Original designation of this product is 703# which is equivalent to Amberlite IRA-68 and AP-9 of foreign products.
