Highly cross-linked polystyrene-divinylbenzene matrix with sulfonic acid functional groups for robust cation exchange capacity.
Excellent chemical and thermal stability, suitable for repeated regeneration cycles in acidic and neutral environments.
Uniform spherical bead morphology ensuring low pressure drop and consistent hydraulic performance in fixed-bed columns.
High total exchange capacity (≥4.8 meq/mL in Na⁺ form) and strong affinity for divalent metal ions such as Ca²⁺ and Mg²⁺.
Low fines content (<0.2%) and high mechanical strength, minimizing resin attrition during backwashing and service operation.
Softening of boiler feed water and process water in power plants and industrial steam systems.
Deminerlization in mixed-bed polishing units for ultrapure water production in semiconductor and pharmaceutical manufacturing.
Removal of heavy metal cations (e.g., Cu²⁺, Ni²⁺, Zn²⁺) from industrial wastewater streams.
Catalytic support and ion-specific separation in fine chemical synthesis and hydrometallurgical recovery processes.
Pretreatment for reverse osmosis (RO) systems to prevent scaling by calcium and magnesium precipitation.
