Description

Oxirane, Methyl-, Polymer With .Alpha.-Butyl-.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl) And Oxirane is a specialized polyether polyol block copolymer, commonly known as a nonionic surfactant or polymeric emulsifier. This compound is engineered to provide exceptional performance as a stabilizer, dispersant, and wetting agent in complex formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and personal care industries seeking to enhance product stability and performance.

Application

• Primary emulsifier and stabilizer in the production of aqueous polymer dispersions for paints and coatings.
• Key additive in polyurethane foam systems to control cell structure and improve foam stability.
• Dispersing agent for pigments and fillers in industrial and decorative coatings to prevent settling and ensure color consistency.
• Stabilizing surfactant in the formulation of household and industrial cleaning products.
• Functional additive in adhesives and sealants to improve wetting and substrate adhesion.
• Emulsifier and viscosity modifier in personal care products such as creams and lotions.
• Component in agricultural adjuvant formulations to enhance the spreading and efficacy of pesticides.
• Processing aid in the manufacture of textile and leather chemicals.

Quality Control

Every batch of our Oxirane, Methyl-, Polymer is produced under a strict quality management system. We ensure consistency and reliability through rigorous in-process and final product testing, which typically includes analysis of hydroxyl value, ethylene oxide/propylene oxide content, viscosity, and water content. Certificates of Analysis (COA) documenting all relevant specifications are available upon request 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 potential oxidation. Keep away from strong oxidizing agents.
