ZGC 107DQ styrene series strongly acidic cation exchange resin
1. Description
The “Hydrolite” brand ZGC107DQ is a sort of cation exchange resin that has sulfonic group (-SO3H) in the styrene-diethylene benzene copolymer with 7% cross-linked degree. It is used mainly to soft hard water and produce pure water, as well as used in the hydro-metallurgy and sugar producing and medicine and nosodium glutamate industry, it can be used as catalyzer and dehydrating agent.
