Strong Acid Cation Ion Exchange Resin, Gel Type, Hydrogen Form

Description

Strong Acid Cation (SAC) Ion Exchange Resin in hydrogen form is a gel-type sulfonated copolymer of styrene and divinylbenzene. The resin contains sulfonic acid functional groups in the H⁺ form, making it ideal for demineralization and deionization processes. Its gel-type matrix provides high exchange capacity, rapid ion transfer, and reliable operation for small inorganic cations. This resin is commonly used in hydrogen cycle operation, mixed-bed systems, condensate polishing, and high-purity water applications. The spherical beads are chemically stable, mechanically strong, and designed for long service life in demanding conditions.

Applications

• Demineralization / deionization units

• Condensate polishing in power plants

• Mixed-bed polishing systems for ultrapure water

• Semiconductor and microelectronics water treatment

• Boiler feed water treatment requiring low salt leakage

• Food and beverage industry water conditioning (acid cycle)

• Pharmaceutical and laboratory deionized water systems

• Chemical processing for acidification and cation removal

• Metal finishing and electroplating (removal of heavy metal cations)
