Description

Benzenesulfonic Acid, 4-Ethenyl-, Calcium Salt, Polymer With 1,4-Diethenylbenzene is a high-performance, cross-linked polymeric resin derived from styrenic monomers. This material is valued for its robust chemical structure and functional properties, making it a critical component in advanced industrial processes. It is primarily utilized in sectors requiring specialized ion-exchange, catalytic, or separation media, such as water treatment, chemical synthesis, and pharmaceutical purification.

Application

• Ion-Exchange Resin: Used in water softening, demineralization, and ultrapure water production for power generation, electronics, and pharmaceuticals.
• Catalyst & Catalyst Support: Serves as a solid acid catalyst or a stable support matrix in organic synthesis and petrochemical refining.
• Chromatography Media: Employed in separation and purification columns for analytical and preparative-scale isolation of fine chemicals and biomolecules.
• Polymer Additive: Functions as a stabilizer, cross-linking agent, or property modifier in specialty polymer formulations.
• Wastewater Treatment: Effective in the selective removal of heavy metal ions and organic contaminants from industrial effluent.
• Pharmaceutical Intermediates: Used in the synthesis and purification steps for active pharmaceutical ingredients (APIs).

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is controlled against stringent specifications for ion-exchange capacity, particle size distribution, moisture content, and chemical stability. Certificates of Analysis (COA) documenting purity and performance parameters are available upon request. Our manufacturing adheres to ISO 9001 quality management principles, ensuring reliability and traceability for global B2B customers.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong acids and organic solvents.
