Highly stable macroporous polystyrene-divinylbenzene matrix engineered for superior mechanical and osmotic shock resistance.
Optimized strong acid cation exchange functionality with sulfonic acid groups, ensuring consistent high capacity across variable feed conditions.
Excellent regeneration efficiency using standard mineral acids (e.g., HCl or H₂SO₄), minimizing chemical consumption and waste generation.
Low fines generation and uniform spherical bead morphology, supporting low pressure drop and long service life in fixed-bed systems.
Compliant with global food-grade and pharmaceutical regulatory requirements (e.g., FDA 21 CFR §173.25, EU Regulation EC No. 1935/2004).
Ultrapure water production for semiconductor manufacturing and microelectronics rinsing processes.
Pretreatment of boiler feedwater in high-pressure steam generation systems to prevent scale and corrosion.
Softening and demineralization in pharmaceutical process water systems (PW, WFI pre-polishing).
Recovery and purification of metal ions in hydrometallurgical leach solutions (e.g., Ni, Co, Cu).
Catalytic support and acid scavenging in fine chemical synthesis and API purification workflows.
