ZGA 302 Type II Styrene Series Strong Basic Anion Exchange Resins

Description

1. Description

Hydrolite 202 is a type of anion exchange resin containing a quaternary ammonium group [N-(CH₃)₂C₂H₄OH] in a styrene-diethylenebenzene copolymer. It is primarily used to produce clean water with characteristics such as high recovery efficiency and large exchange capacity, and is particularly suitable for water sources with high salt content.
