Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,2-Ethanediol And 1,1-Methylenebisisocyanatobenzene CAS NO 65916-86-1 is a high-performance polyurethane prepolymer or polyurethane elastomer derived from adipic acid, butanediol, ethylene glycol, and MDI. This engineered polymer offers a critical balance of mechanical strength, flexibility, and chemical resistance for demanding industrial applications. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Coatings and Paints: Used as a binder in industrial and protective coatings for metals, concrete, and plastics, providing excellent abrasion resistance, gloss, and weatherability.
• Adhesives and Sealants: Serves as a key component in formulating structural adhesives, laminating adhesives, and flexible sealants with strong bonding strength and environmental resistance.
• Elastomers and Castable Urethanes: A fundamental raw material for producing polyurethane elastomers used in wheels, rollers, gaskets, and industrial parts requiring toughness and resilience.
• Textile and Leather Finishing: Applied in coatings for synthetic leather, waterproof fabrics, and textile finishes to impart durability, softness, and water repellency.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites for the automotive and aerospace sectors.
• Encapsulation and Potting Compounds: Utilized in electronics and electrical applications to protect components from moisture, vibration, and thermal shock.

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 acid number are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and premature reaction. Isolate from strong acids, bases, and oxidizing agents.
