Description

Poly(Tetrahydrofuran)-Co-(Ethyleneoxide) is a high-performance block copolymer, also known as a polyether glycol, synthesized from tetrahydrofuran and ethylene oxide monomers. This versatile polymer is valued for its excellent flexibility, low-temperature properties, and compatibility with a wide range of chemical systems, making it a critical intermediate for advanced material formulations. It is essential for manufacturers in the polyurethane, coatings, and specialty elastomer industries seeking to enhance product durability and performance.

Application

• Polyurethane Elastomers & Spandex Fibers: Serves as a key soft segment polyol, imparting superior elasticity, hydrolytic stability, and low-temperature flexibility to the final polymer.
• Thermoplastic Polyurethanes (TPU): Used as a macrodiol to produce high-performance TPUs for applications in automotive parts, wire and cable jacketing, and medical tubing.
• Coatings, Adhesives, Sealants, and Elastomers (CASE): A fundamental building block for formulating high-resilience, abrasion-resistant, and weatherable coatings and sealants.
• Specialty Surfactants & Demulsifiers: Acts as a non-ionic surfactant precursor or demulsifier component in the petroleum and agrochemical industries.
• Lubricants and Functional Fluids: Employed as a base or additive in synthetic lubricants and hydraulic fluids due to its viscosity-temperature characteristics.
• Pharmaceutical & Cosmetic Excipients: Used in controlled drug delivery systems and as a solubilizer or carrier in topical formulations (subject to appropriate grade and purity).

Quality Control

Our Poly(Tetrahydrofuran)-Co-(Ethyleneoxide) is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent properties such as hydroxyl value, molecular weight distribution, and water content. Certificates of Analysis (COA) detailing key specifications are available upon request. We can support compliance with relevant standards for industrial and specialized applications.

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) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and oxidation. Keep away from strong bases and incompatible materials.
