Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,2-Ethanediol, 1,6-Hexanediol And 1,1-Methylenebis4-Isocyanatobenzene CAS NO 29014-53-7 is a high-performance, segmented polyurethane or polyurethane-urea copolymer. This engineered polymer is valued for its exceptional balance of mechanical strength, flexibility, and chemical resistance, derived from its specific multi-component composition. It is a critical material for formulators and manufacturers in industries requiring durable, high-performance elastomers and coatings.

Application

• High-Performance Elastomers and Thermoplastic Polyurethanes (TPU): Used in the production of industrial belts, hoses, gaskets, and seals that demand excellent abrasion resistance and dynamic performance.
• Specialty Coatings and Adhesives: Serves as a key resin for formulating protective coatings, sealants, and high-strength adhesives with superior weatherability and adhesion to diverse substrates.
• Textile and Fiber Finishing: Applied as a durable, flexible coating or binder for technical textiles, synthetic leather, and non-woven fabrics to enhance durability and water resistance.
• Automotive Components: Utilized in under-the-hood parts, interior trim, and exterior protective elements where thermal stability and oil/fuel resistance are paramount.
• Medical Device Polymers: Suitable for certain medical tubing, catheter components, and device housings requiring biocompatibility and specific mechanical properties (subject to appropriate regulatory compliance and grade).
• Industrial Rollers and Wheels: Formulated into castable polyurethanes for manufacturing rollers, wheels, and impact pads used in material handling and machinery.

Quality Control

Our production of this polyurethane copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including molecular weight distribution, hydroxyl/isocyanate content, viscosity, and thermal properties to ensure batch-to-batch consistency for your formulations. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment. We support compliance with relevant global regulatory frameworks such as REACH.

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); keep the original container tightly sealed to prevent absorption of atmospheric moisture, which can affect processing properties. Keep away from strong acids, bases, and oxidizing agents.
