Macroporous Strongly Acidic Styrene-based

Cation Exchange Resin


D001 is a macro-porous strongly acidic cation exchange resin of the sulphonated polystyrene type. With its uniform and solid structure and low rate of repetitive reversion and expansion, it performs with good anti-osmatic efficiency and shock resistance. The mesh porosity of the resin does not vary from solution swelling, and it remains with good exchange and adsorption performance in organic solutions. Also, it can be used in water demineralization and applied as catalyst thro organic synthesis.
