Description

Poly[Di(Ethylene Glycol)/Glycerol-Alt-Adipic Acid], Polyol CAS NO 26760-54-3 is a specialized, water-soluble polyester polyol derived from the alternating copolymerization of a diol/glycerol blend with adipic acid. This chemistry provides a versatile building block with a unique balance of hydroxyl functionality, flexibility, and hydrolytic stability, making it a valuable intermediate for high-performance polymer synthesis. It is primarily sought by formulators and manufacturers in the polyurethane, adhesive, coating, and resin industries seeking to tailor material properties such as elasticity, adhesion, and chemical resistance.

Application

• Polyurethane Systems: A key soft segment component for flexible foams, elastomers, coatings, and adhesives, imparting resilience and low-temperature flexibility.
• Waterborne Polyurethane Dispersions (PUDs): Used in the synthesis of environmentally friendly coatings for textiles, leather finishing, and industrial paints.
• Adhesives & Sealants: Serves as a polymeric polyol to enhance the tack, peel strength, and durability of polyurethane-based adhesive formulations.
• Resin Modification: Acts as a reactive modifier or crosslinker in alkyd, polyester, and other resin systems to improve flexibility and impact resistance.
• Specialty Elastomers: Employed in the production of castable and thermoplastic polyurethane elastomers for gaskets, wheels, and industrial parts.
• Composite Materials: Functions as a matrix resin component or plasticizer in fiber-reinforced composites and gel coats.

Quality Control

Our Poly[Di(Ethylene Glycol)/Glycerol-Alt-Adipic Acid] Polyol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of hydroxyl value, acid value, viscosity, and water content. Certificates of Analysis (COA) detailing these specifications are available for every shipment upon request, providing full traceability and compliance assurance for your production processes.

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 product is hygroscopic (moisture-sensitive). To prevent moisture absorption and potential property changes, ensure containers are sealed immediately after use and consider storage under a dry inert atmosphere for long-term holding.
