High-capacity strong acid cation exchange resin based on sulfonated polystyrene-divinylbenzene matrix.
Optimized for high selectivity and efficient removal of multivalent cations (e.g., Ca²⁺, Mg²⁺, Fe³⁺) in softening and demineralization applications.
Excellent physical and chemical stability across wide pH range (0–14) and resistant to osmotic shock during regeneration cycles.
Uniform spherical bead morphology ensures low pressure drop and consistent hydraulic performance in fixed-bed systems.
Regenerable with standard sodium chloride or acid solutions, supporting sustainable operation and reduced operational costs.
Industrial water softening for boiler feedwater and cooling tower makeup.
Pretreatment in reverse osmosis (RO) and mixed-bed polishing systems.
Removal of hardness ions and heavy metals from process water in food & beverage production.
Cation exchange in pharmaceutical-grade purified water (PW) and water-for-injection (WFI) systems.
Effluent treatment for metal recovery and wastewater conditioning in electroplating and metal finishing industries.
