Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,4-Cyclohexanedimethanol And 1,1'-Methylenebis[4-Isocyanatobenzene] is a high-performance thermoplastic polyurethane (TPU) or polyurethane elastomer, known for its exceptional balance of mechanical strength, chemical resistance, and processing versatility. This engineered polymer is valued for delivering durable, flexible, and resilient properties critical for demanding industrial applications. It is primarily sought by manufacturers in the automotive, wire and cable, industrial machinery, and specialty film sectors for components requiring long-term reliability under stress.

Application

• Automotive Components: Used in seals, gaskets, hoses, and interior trim parts due to its abrasion resistance and durability.
• Wire & Cable Jacketing: Provides excellent insulation, flexibility, and resistance to oils, chemicals, and environmental stress cracking.
• Industrial Belts & Rollers: Ideal for conveyor belts, drive rollers, and timing belts where high tensile strength and low wear are required.
• Technical Films & Sheets: Employed in breathable membranes, protective films, and industrial laminates for its toughness and barrier properties.
• Footwear & Sporting Goods: Used in soles, midsoles, and performance gear for its cushioning, flexibility, and resilience.
• Medical Device Components: Suitable for non-implantable parts requiring biocompatibility, clarity, and sterilization resistance.
• Industrial Hose & Tubing: Manufactured into hoses for hydraulic systems, fuel lines, and pneumatic applications.
• Adhesives & Sealants: Serves as a base polymer for high-performance, flexible adhesives and coating systems.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like hardness, tensile strength, and melt flow index. Quality is verified through a suite of analytical techniques including FTIR, GPC, and DSC. A comprehensive Certificate of Analysis (COA) detailing physical, mechanical, and rheological properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and strong oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption, which can affect processing characteristics.
