D301 Macroporous Styrene Weak Base Anion Exchange Resin For Sugar Decolor
This product is a weakly basic anion exchange resin featuring tertiary amine groups [-N(CH₃)₂] on a macroporous styrene-divinylbenzene copolymer. Its mild alkalinity enables effective removal of organic pigments, inorganic acids, and silicate ions in acidic and near-neutral media. It also adsorbs larger molecular impurities and performs well in non-aqueous solutions. This resin offers high regeneration efficiency, large exchange capacity, strong resistance to contamination, and excellent mechanical strength.
