Description

Butane, 1,2-Epoxy-, Polymer With Ethylene Oxide is a polyether polyol, a versatile chemical intermediate produced by the copolymerization of butylene oxide and ethylene oxide. This compound is valued for its ability to impart specific hydrophilicity, flexibility, and reactivity into polymer chains, making it a critical building block for advanced materials. It is primarily sought by formulators and manufacturers in the polyurethane, surfactant, and specialty chemical industries for creating tailored performance products.

Application

• Polyurethane Foam Production: Used as a key polyol component in flexible and rigid foams, influencing cell structure, softness, and resilience.
• Surfactants & Emulsifiers: Serves as a hydrophilic backbone for non-ionic surfactants used in detergents, agrochemicals, and personal care products.
• Lubricants and Functional Fluids: Acts as a base or additive in synthetic lubricants, hydraulic fluids, and metalworking fluids due to its stability and solubility properties.
• Coating and Adhesive Formulations: Incorporated into polyurethane dispersions (PUDs) and adhesives to modify flexibility, adhesion, and water resistance.
• Pharmaceutical and Cosmetic Excipients: Employed in the synthesis of polyethylene glycol (PEG) derivatives and other carriers for drug delivery and cosmetic formulations.
• Chemical Intermediate: Utilized as a reactive intermediate for further chemical modifications, including esterification and etherification reactions.
