ZGA 351SC macroporous styrene series of strongly basic anion exchange resins

Description

1. Description:

“Hydrolite” ZGA 351SC is a type of anion exchange resin containing a quaternary ammonium group [-N(CH3)3OH] in a styrene-diethylenebenzene copolymer with a macroporous structure. Strongly acidic cationic resins, _along with _weakly acidic cationic resins, are used to produce pure and ultrapure water in a two-layer cationic filter system. The true density and particle size distribution differ significantly between the strong and weak resins, resulting in excellent hydrodynamic properties and a clear separation effect.

2. Implemented standards: GB/T 16580-1996 DL/T519-2004 SH2605.07-2003
