Macroporous Strongly Acidic
Styrene-based Mixed-bed Cation Exchange Resin


D001MB is a macroporous strongly acidic cation exchange resin of the sulphonated polystyrene type. With its uniform and solid structure and low swelling rate of ionic state transition, it performs with good anti-osmatic efficiency and shock resistance. It is mainly combined with D201MB to be used in processing mix-bed pure water preparations, with equivalent properties as US Model #IR-200.
