Description

Benzenesulfonic Acid, Ethenyl-, Ammonium Salt, Polymer With Diethenylbenzene is a synthetic, cross-linked polymeric resin with ion-exchange properties. This material is valued for its strong acid functionality and robust physical structure, making it a critical component in separation and purification processes. It is primarily needed by industries involved in water treatment, chemical synthesis, and pharmaceutical manufacturing for applications requiring selective ion capture or catalysis.

Application

• Industrial Water Treatment: Used as a strong acid cation exchange resin for demineralization, dealkalization, and metal ion removal from process water and wastewater.
• Chemical Catalysis: Serves as a solid acid catalyst in organic synthesis reactions, offering advantages in separation and reusability over liquid acids.
• Pharmaceutical Purification: Employed in the purification and isolation of active pharmaceutical ingredients (APIs) and intermediates through ion-exchange chromatography.
• Sugar & Sweetener Processing: Utilized for decolorization, deashing, and ion removal in the refining of sugar syrups and high-fructose corn syrup.
• Hydrometallurgy: Applied in the recovery and separation of valuable metals, such as uranium, rare earth elements, and precious metals, from leach solutions.
• Condensate Polishing: A key resin in mixed-bed or separate-bed units for purifying boiler feedwater and steam condensate in power plants.

Quality Control

Our ion exchange resins are manufactured under a strict quality management system. Each batch undergoes comprehensive testing for key parameters including ionic form, total exchange capacity, moisture content, and particle size distribution to ensure consistent performance and reliability. Certificates of Analysis (COA) detailing these specifications are available upon request.

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). Keep away from strong oxidizing agents. As the product is supplied in a moist state, do not allow it to dry out or freeze, as this may cause irreversible damage to the polymer matrix.
