Description

Hexanedioic Acid, Polymer With 1,4-Butanediol And 1,1-Methylenebis4-Isocyanatobenzene is a high-performance polyurethane prepolymer or thermoplastic polyurethane (TPU) elastomer derived from adipic acid, 1,4-butanediol (BDO), and methylene diphenyl diisocyanate (MDI). This engineered polymer is valued for its excellent balance of mechanical strength, flexibility, and chemical resistance, making it a critical material for demanding industrial applications. It is primarily sought by manufacturers in the elastomer, adhesive, coating, and specialty plastics sectors for producing durable components, sealants, and high-performance films.

Application

• Thermoplastic Polyurethane (TPU) Elastomers: Used in injection molding and extrusion for manufacturing seals, gaskets, hoses, and cable sheathing.
• High-Performance Coatings and Adhesives: Serves as a key binder in formulations requiring superior abrasion resistance, flexibility, and adhesion to various substrates.
• Synthetic Leather and Textile Coatings: Provides a durable, flexible, and breathable film layer for artificial leather, waterproof fabrics, and protective apparel.
• Footwear Components: Used in the production of shoe soles, heel counters, and other parts requiring excellent wear resistance and comfort.
• Automotive Parts: Applied in the manufacturing of interior trim, exterior protective films, and vibration-damping components.
• Medical Device Tubing and Film: Suitable for applications requiring biocompatibility, clarity, and flexibility, subject to appropriate regulatory compliance.
• Industrial Rollers and Belts: Provides the necessary toughness and resilience for conveyor belts, printing rollers, and other machinery parts.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including molecular weight distribution, isocyanate (NCO) content, viscosity, and thermal properties to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request, supporting compliance with relevant industry and customer-specific requirements.

Storage

Preserve in a tightly closed, moisture-proof container under a dry, inert atmosphere (e.g., nitrogen) if in prepolymer form. Store in a cool, dry, well-ventilated area away from heat, open flame, and sources of moisture. Typical recommended storage temperature is between 15°C and 25°C. Protect from light. Under these conditions, the material is typically stable for 12-24 months from the date of manufacture. Always check the specific technical data sheet for the grade in use.
