Description

1,4-Benzenedicarboxylic Acid, Dimethyl Ester, Polymer With 1,4-Butanediol, Hexanedioic Acid And 1,1-Methylenebis4-Isocyanatobenzene is a high-performance thermoplastic polyurethane (TPU) elastomer, synthesized from key monomers including dimethyl terephthalate, butanediol, adipic acid, and MDI. This engineered polymer is valued for its exceptional balance of elasticity, abrasion resistance, and mechanical strength, making it a versatile material for demanding applications. It is primarily sought by manufacturers in the automotive, industrial machinery, and consumer goods sectors seeking durable, flexible components. CAS No. 90588-26-4.

Application

• Automotive Components: Used in the production of durable seals, gaskets, hoses, and cable sheathing due to its oil and abrasion resistance.
• Industrial Belts and Rollers: Ideal for manufacturing conveyor belts, drive belts, and industrial rollers requiring high tensile strength and flexibility.
• Footwear: Employed in the soles and components of high-performance athletic, safety, and casual footwear for superior cushioning and wear life.
• Extruded and Molded Technical Parts: Serves as a key material for injection-molded or extruded parts like seals, diaphragms, and bushings in machinery.
• Wire and Cable Insulation: Provides excellent insulating properties and mechanical protection for specialized cables.
• Consumer Goods: Used in the manufacture of durable, flexible items such as watch straps, phone cases, and sporting goods.

Quality Control

Our thermoplastic polyurethane is manufactured under a strict quality management system. Each batch undergoes comprehensive testing for key parameters including intrinsic viscosity, melt flow index, hardness (Shore A/D), tensile strength, and elongation at break to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. As a polymer, it is generally stable but should be protected from prolonged exposure to high humidity to prevent potential hydrolysis of ester linkages.
