Description

Hexanedioic Acid, Polymer With 1,6-Hexanediol And 1,1-Methylenebis4-Isocyanatobenzene is a high-performance polyurethane prepolymer or thermoplastic polyurethane (TPU) based on adipic acid, 1,6-hexanediol, and MDI (4,4'-methylenebis(phenyl isocyanate)). This engineered polymer is valued for its excellent balance of mechanical strength, chemical resistance, and processing versatility. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing specialized thermoplastic polyurethanes for demanding applications.

Application

• High-Performance Coatings & Paints: Used as a binder in industrial and protective coatings requiring superior abrasion resistance, chemical durability, and weatherability.
• Adhesives & Sealants: Serves as a key component in formulating structural adhesives, laminating adhesives, and flexible sealants with strong bonding and elastic properties.
• Thermoplastic Polyurethane (TPU) Production: Acts as a prepolymer or direct component in manufacturing TPU granules for injection molding, extrusion, and calendaring processes.
• Elastomers & Castables: Utilized in the production of cast polyurethane elastomers for industrial rollers, wheels, gaskets, and impact-absorbing parts.
• Textile & Leather Finishing: Applied in coatings and finishes to enhance the durability, water resistance, and feel of synthetic leather and technical textiles.
• Wire & Cable Insulation: Used in formulations for flexible, flame-retardant, and durable insulation and jacketing materials.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, hydroxyl value, and molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers (typically between 15°C and 25°C). Keep away from strong bases and organic solvents. Under these conditions, the product is stable for the period indicated on the label. Allow the material to reach room temperature before use if stored under cooler conditions.
