Description

Ethanol, 2,2'-Oxybis-, Polymer With Methyloxirane CAS NO 132435-10-0 is a high-performance polyether polyol, specifically a block copolymer derived from diethylene glycol (2,2'-oxybis-ethanol) and propylene oxide (methyloxirane). This chemical is engineered to provide exceptional control over polymer properties, making it a critical intermediate for advanced material synthesis. It is primarily utilized by formulators and manufacturers in the polyurethane, coatings, and specialty chemical industries seeking to tailor flexibility, hydrophilicity, and reactivity in their final products.

Application

• Polyurethane Foam Production: Serves as a key polyol component for flexible and semi-flexible foams, influencing cell structure and softness.
• Coatings & Adhesives: Used in the formulation of high-performance polyurethane coatings, sealants, and adhesives to enhance elasticity and adhesion.
• Elastomer Manufacturing: Acts as a building block for thermoplastic polyurethane (TPU) and other elastomers, providing tailored mechanical properties.
• Surfactants & Demulsifiers: Utilized as a hydrophilic intermediate in the synthesis of nonionic surfactants and oilfield chemicals.
• Pharmaceutical & Cosmetic Excipients: Employed in the production of specialized polymers for controlled drug delivery and cosmetic formulations.
• Functional Fluid Additives: Incorporated into lubricants and hydraulic fluids as viscosity modifiers and performance enhancers.

Quality Control

Our Ethanol, 2,2'-Oxybis-, Polymer With Methyloxirane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in critical parameters such as hydroxyl value, molecular weight distribution, and viscosity. Certificates of Analysis (COA) documenting purity and specifications 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep containers tightly sealed when not in use to prevent absorption of atmospheric moisture.
