Description

Ethylene Oxide Polymer CAS NO 9002-90-8 is a versatile synthetic polymer formed from the polymerization of ethylene oxide, widely recognized for its hydrophilic properties and solubility in water. This material is crucial for creating high-performance surfactants, thickeners, and functional additives across numerous industrial sectors. Key industries that rely on this polymer include pharmaceuticals, personal care, textiles, and agrochemicals, where it serves as a foundational component for product formulation and performance enhancement.

Application

• Primary raw material for the synthesis of nonionic surfactants (e.g., ethoxylated alcohols, alkylphenol ethoxylates).
• Key ingredient in pharmaceutical formulations, used as a solubilizer, emulsifier, and in controlled-release drug delivery systems.
• Essential component in personal care and cosmetic products, such as creams, lotions, and shampoos, for viscosity modification and stabilization.
• Used in textile processing as a lubricant, softener, and anti-static agent.
• Employed in the production of polyurethane foam as a reactive polyol component.
• Applied in agrochemicals as an adjuvant to improve the spreading and absorption of pesticides and herbicides.
• Utilized in industrial cleaning formulations and detergent blends for enhanced cleaning efficacy.
• Serves as a base polymer for further chemical modification to create specialized copolymers.

Quality Control

Our Ethylene Oxide Polymer is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including determination of molecular weight distribution, hydroxyl value, viscosity, and moisture content. Certificates of Analysis (COA) documenting all critical parameters are available for every shipment. Production can adhere to relevant standards such as USP-NF, Ph. Eur., or specific customer requirements 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). This product is hygroscopic (moisture-sensitive) and must be kept in original packaging or a moisture-proof container to prevent caking and degradation. Keep away from strong oxidizing agents.
