Advantages
This product is a type of weak alkaline anion exchange resin with polyamine groups which is achieved by aminolysis of acrylic acid serial copolymer crosslinking high polymer with macroporous structure. It has properties like large exchange capacity, fast exchange speed, good separating effect, easy to elution, low consumption of regenerated water, small volume change, strong pollution resistibility, and good chemical stability.
This product is equivalent to Purolite A830, A-561, and XA-3414 of foreign products.
