Description

Oxirane, Methyl-, Polymer With Oxirane, Monomethyl Ether is a polyether polyol, specifically a block copolymer of propylene oxide and ethylene oxide. This versatile chemical intermediate is valued for its ability to impart controlled hydrophilicity, surfactant properties, and flexibility to final formulations. It is essential for manufacturers in the polyurethane, coatings, and personal care industries seeking to fine-tune product performance.

Application

• Polyurethane Foam Manufacture: Acts as a key polyol component in flexible and rigid foams, influencing cell structure, softness, and resilience.
• Surfactants & Emulsifiers: Serves as a crucial building block for non-ionic surfactants used in detergents, agrochemicals, and textile processing.
• Coatings & Adhesives: Used to modify properties such as flexibility, adhesion, and moisture resistance in various polymer coatings and adhesive systems.
• Personal Care Products: Employed in the synthesis of emulsifiers and conditioning agents for creams, lotions, and hair care formulations.
• Lubricants and Functional Fluids: Functions as a base or additive in synthetic lubricants, hydraulic fluids, and metalworking fluids.
• Pharmaceutical Excipients: Used in the production of certain polymeric carriers and solubilizing agents for drug delivery systems.

Quality Control

Our Oxirane, Methyl-, Polymer With Oxirane, Monomethyl Ether is produced under a strict quality management system. Each batch is tested to ensure consistent hydroxyl value, molecular weight distribution, viscosity, and moisture content. Certificates of Analysis (COA) documenting these parameters are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture uptake and oxidation.
