High functional group density for superior anion removal capacity in weakly acidic and neutral conditions.
Excellent chemical stability in alkaline environments, enabling robust performance during caustic regeneration.
Fast kinetics and low pressure drop due to uniform macroporous bead structure and optimized particle size distribution.
Low soluble organic extractables, meeting stringent purity requirements for pharmaceutical and fine chemical applications.
Thermally stable up to 100°C, supporting operation in elevated temperature process streams.
Removal of organic acids (e.g., acetic, citric, oxalic) from process streams in biotechnology and fermentation broths.
Decolorization and purification of sugar syrups and starch hydrolysates in food and beverage manufacturing.
Recovery and concentration of carboxylic acids in downstream processing of bio-based chemicals.
Pretreatment of feedwater for mixed-bed polishing systems to protect strong base resins from organic fouling.
Neutralization and capture of acidic contaminants in pharmaceutical intermediate synthesis and purification.
