Dual Bed Macroporous Strong Acid
Styrene Series Cation Exchange Resin


D001DB is a macroporous strongly acidic styrene-based cation exchange resin with a sulphonic acid functional group, 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, D001DB resin is primarily used in dual-bed down-flow water purification system that include cation-exchange layer for processing decolored or deodorized pure water within various industries.
