Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,1-Methylenebis4-Isocyanatobenzene And 2,2-Oxybisethanol CAS NO 32517-10-5 is a specialized polyurethane prepolymer or resin derived from adipic acid, butanediol, a diisocyanate, and diethylene glycol. This engineered polymer is valued for its ability to impart specific mechanical properties, chemical resistance, and processing characteristics to final formulations. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-performance polyurethane dispersions (PUDs) and thermoplastic polyurethanes (TPUs).

Application

• High-Performance Coatings: Used as a key resin component in industrial, automotive, and protective coatings for enhanced durability, flexibility, and chemical resistance.
• Adhesives & Sealants: Serves as a base polymer in formulating structural adhesives, laminating adhesives, and flexible sealants with strong bonding and elastic properties.
• Elastomers and Castables: Employed in the production of cast polyurethane elastomers for wheels, rollers, gaskets, and industrial parts requiring abrasion resistance.
• Polyurethane Dispersions (PUDs): Acts as a precursor for water-based PUDs used in eco-friendly coatings, textiles, and leather finishing.
• Thermoplastic Polyurethane (TPU): A building block for TPU granules used in injection molding, extrusion, and 3D printing filaments.
• Composite Materials: Utilized as a matrix or binder in fiber-reinforced composites and specialty encapsulants.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as NCO content, hydroxyl value, viscosity, and acid number are strictly monitored. Certificates of Analysis (COA) detailing all relevant specifications are available upon request. Our manufacturing processes adhere to ISO 9001 quality management principles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive (hygroscopic) and may react with atmospheric moisture; ensure containers are sealed when not in use. Keep away from heat, sparks, and open flame. For long-term storage, consider storing under a dry inert atmosphere (e.g., nitrogen).
