Strongly Basic Styrene-based Anion Exchange Resin

PRODUCT DATA SHEET:

201X4, aka 711 is a premium grade strongly basic anion exchange resin of the type I, with a clear gel structure. This resin is cross-linked by the polystyrene group, particles of which are with complete bead integrity. Additionally, its high regeneration efficiency and excellent rinse performance give premium efficacy to the application of water demineralization in various industries, and of wastewater treatment as well as the separation of anionic metal complex compound, etc.
