Description

Sulfonated Ethenylbenzene Homopolymer is a synthetic polymer derived from styrene, characterized by the presence of sulfonic acid groups attached to the aromatic rings of the polymer backbone. This functionalization imparts strong cation exchange properties, making it a critical material for separation, purification, and catalysis processes. It is essential for industries requiring high-performance ion exchange resins, including water treatment, pharmaceuticals, chemical synthesis, and food & beverage processing.

Application

• Ion Exchange Resins: Primary component in the manufacture of strong acid cation exchange resins for water softening, demineralization, and ultrapure water production.
• Pharmaceutical Purification: Used in chromatography columns for the purification of antibiotics, vitamins, and other active pharmaceutical ingredients (APIs).
• Catalysis: Serves as a solid acid catalyst in organic synthesis reactions, such as esterification and alkylation, offering advantages in separation and reusability.
• Sugar & Sweetener Processing: Employed in the decolorization and deashing of sugar syrups and high-fructose corn syrup.
• Hydrometallurgy: Facilitates the recovery and separation of valuable metals like copper, nickel, and rare earth elements from process streams.
• Chemical Processing: Used for the removal of cations and catalysts from reaction mixtures in fine chemical and petrochemical manufacturing.

Quality Control

Our Sulfonated Ethenylbenzene Homopolymer is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance as a resin precursor, with key parameters including sulfonation degree, particle size distribution, and total exchange capacity. Certificates of Analysis (COA) documenting purity and specifications are provided with every shipment to ensure traceability and compliance with your quality requirements.

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, which can affect performance.
