ZGA307MB styrene series strong base anion exchange resins

Description

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.
