Description

Calciumpolystyrenesulphonate is a synthetic, cross-linked polymer in its calcium salt form, widely recognized for its exceptional ion-exchange capabilities. This compound is crucial for applications requiring the selective removal or exchange of specific ions from solutions, offering high capacity and chemical stability. It is an essential material for industries such as water treatment, pharmaceuticals, and chemical processing, where precise ion control is paramount for product quality and process efficiency.

Application

• Water Softening & Purification: Used as a cation exchange resin to remove calcium, magnesium, and other hardness ions from industrial process water and feedwater for boilers.
• Pharmaceutical Manufacturing: Employed as an excipient in tablet formulations, particularly as a disintegrant to promote the breakup of tablets in the gastrointestinal tract.
• Food & Beverage Processing: Acts as a processing aid for juice clarification, wine stabilization, and the removal of unwanted cations to control taste and improve product stability.
• Chemical Synthesis & Catalysis: Serves as a solid support for catalysts or as an ion-exchange medium in various organic synthesis and purification steps.
• Laboratory & Analytical Chemistry: Utilized in chromatography columns for the separation and purification of ionic compounds and biomolecules.
• Hydrometallurgy: Applied in the recovery and separation of valuable metal ions from leach solutions in mining operations.

Quality Control

Our Calciumpolystyrenesulphonate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for ion-exchange capacity, particle size distribution, moisture content, and purity. Certificates of Analysis (COA) documenting these parameters are provided with every shipment. We can supply grades suitable for industrial, technical, and more demanding applications, with quality protocols aligned with cGMP where required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials.
