D201 MB styrene series macroporous strongly basic anion exchange resin
D201 MB is a sort of anion exchange resin that has quaternary ammonium group [-N(CH3)3OH] in the styrene-diethylene benzene copolymer with macroporous structure. It is used mainly to produce pure water and ultra pure water in the mixed bed system, with the characteristics such as excellent hydraulics trait and physical stability and anti oxidation ability.
Executing standards: GB/T 16580-2008 DL/T 519-2014
