This product is a macroporous structure of a methacrylate copolymer cross-linked polymer. The polyamine-based weakly basic ion exchange resin obtained by amine hydrolysis of polyethene polyamine has large exchange capacity, small volume change and high mechanical strength. It has good chemical stability, anti-pollution, superior oxidation resistance and fast exchange speed.
The original grade of this product is 703#, which is equivalent to foreign brands: American Amberlite IRA-67/68; Germany: AP-9
