Macroporous Strongly Acidic
Styrene-based Cation Exchange Resin


D001FB is a macroporous strongly acidic styrene-based cation exchange resin with sulphonic acid functional groups, synthesized by special technology. With its highly uniform and solid structure plus low swelling rate after reversible ionic state transition, this resin performs with good anti-osmotic efficiency and shock resistance.

By being largely exchanged with both strong and weak inorganic cations as well as organic cations and nonpolar organic molecules, D001FB resin is primarily filled within cation-bed column of floating-bed reverse-flow deionization system in which anion-bed column is usually post-placed in parallel for processing decolored or deodorized pure water within various industries.
