ZGA 307SF styrene series anion resin

Description

1. Description:

Hydrolite ZGA 307SF anion resin is a type of anion resin with a quaternary ammonium group [-N(CH3 ₎ 3OH _] in a styrene-diethylenebenzene copolymer with a 7% crosslinking degree. It is used primarily for the production of pure and ultrapure water in two-layer anion filters, two-compartment anion systems, floating bed anion systems, and two-compartment floating bed systems.

2. Standards implemented: GB/T13660-1992 DL/T519-2004 SH2605.06-2003
