Description

1,3-Benzenedicarboxylic acid, polymer with 1,4-butanediol, 1,3-diisocyanatomethylbenzene, hexanedioic acid and 1,6-hexanediol is a high-performance thermoplastic polyurethane (TPU) or polyurethane elastomer, engineered for superior mechanical properties and chemical resistance. This copolymer is valued for its excellent balance of flexibility, durability, and processability, making it a critical material for demanding industrial applications. It is primarily sought by manufacturers in the automotive, wire & cable, industrial machinery, and specialty film sectors seeking reliable elastomeric components.

Application

• Automotive Components: Used in seals, gaskets, hoses, and cable sheathing due to its oil, grease, and abrasion resistance.
• Wire & Cable Insulation: Provides excellent insulation, flexibility, and durability for industrial and specialty cables.
• Industrial Belts & Rollers: Serves as a key material for high-performance conveyor belts, drive belts, and rollers requiring toughness.
• Technical Films & Sheets: Employed in the production of breathable, waterproof membranes and protective sheets.
• Footwear & Sporting Goods: Used in soles, midsoles, and other components where cushioning and wear resistance are paramount.
• Medical Device Tubing: Suitable for applications requiring biocompatibility, kink resistance, and clarity (subject to specific grade qualification).
• Industrial Hose Linings: Provides a protective, flexible lining for hoses handling solvents, oils, and abrasive slurries.
• Adhesives & Sealants: Acts as a base polymer for high-strength, flexible adhesive and sealant formulations.

Quality Control

Our thermoplastic polyurethane polymers are manufactured under a stringent quality management system. Each batch is tested against key parameters including intrinsic viscosity, melt flow index, hardness (Shore A/D), tensile strength, and elongation at break to ensure consistent performance and batch-to-batch reliability. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Production can adhere to ISO 9001 standards, and specific grades can be developed to meet customer-defined requirements.

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 incompatible materials such as strong acids, bases, and oxidizing agents. Under these conditions, the product remains stable for extended periods.
