ZGA307MB styrene series strong base anion exchange resins

ZGA307MB styrene series strong base anion exchange resins 1. Description “Hydrolite” ZG 307MB is a type of anion exchange resin containing a quaternary ammonium group [-N(CH3 ) 3OH ] in a styrene-diethylenebenzene copolymer with a 4% degree of crosslinking. It is used primarily to produce pure and ultrapure water in mixed-bed systems with characteristics such as excellent hydraulic properties and physical stability. 2.
