Description

Poly[1,6-Hexanediol/Neopentyl Glycol/Di(Ethylene Glycol)-Alt-Adipic Acid] Diol is a specialized, hydroxyl-terminated polyester polyol engineered for high-performance polymer synthesis. This compound is valued for its ability to impart excellent flexibility, hydrolytic stability, and low-temperature properties to final products. It is a critical raw material for manufacturers in the polyurethane, coatings, and adhesives industries seeking to enhance the durability and performance of their formulations.

Application

• Polyurethane Elastomers & Foams: Serves as a key soft segment component for producing flexible, resilient, and durable elastomers, as well as flexible and microcellular foams.
• High-Performance Coatings & Inks: Used in the synthesis of polyester resins for coatings that require excellent adhesion, chemical resistance, and flexibility.
• Adhesives & Sealants: Imparts toughness and flexibility to hot-melt, moisture-curing, and reactive polyurethane adhesive systems.
• Thermoplastic Polyurethanes (TPU): A fundamental building block for creating TPUs with tailored hardness, elasticity, and processing characteristics.
• Synthetic Leather & Artificial Leather Finishes: Used in binders and topcoats to achieve a soft, supple hand feel and superior abrasion resistance.
• Composite Materials: Functions as a polymeric plasticizer or modifier in various composite systems to improve impact strength and flexibility.

Quality Control

Our Poly[1,6-Hexanediol/Neopentyl Glycol/Di(Ethylene Glycol)-Alt-Adipic Acid] Diol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent hydroxyl value, acid value, viscosity, and moisture content, meeting the precise specifications required for advanced polymer applications. Certificates of Analysis (COA) documenting these key parameters 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, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To prevent moisture uptake and potential property changes, containers must be kept tightly sealed when not in use and under a dry inert atmosphere (e.g., nitrogen) for long-term storage.
