Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,2-Ethanediol And 1,1-Methylenebis4-Isocyanatobenzene CAS NO 27083-55-2 is a high-performance thermoplastic polyurethane (TPU) elastomer synthesized from adipic acid, chain extenders, and MDI. This engineered polymer is valued for its exceptional balance of mechanical toughness, chemical resistance, and versatile processing characteristics. It is a critical material for manufacturers in the automotive, industrial machinery, and consumer goods sectors seeking durable, flexible components. The material's properties can be precisely tailored through its formulation, making it suitable for a wide range of demanding applications.

Application

• Automotive Components: Used in the production of durable seals, gaskets, hoses, and cable sheathing due to its oil and abrasion resistance.
• Industrial Rollers and Wheels: Ideal for manufacturing high-load-bearing rollers, conveyor belt components, and casters that require resilience and low wear.
• Technical Molding: Employed in injection molding and extrusion for producing complex, high-performance parts like seals, diaphragms, and protective covers.
• Wire and Cable Insulation: Serves as a premium jacketing material offering excellent flexibility, tear strength, and environmental stability.
• Consumer and Sporting Goods: Found in products requiring a soft-touch, durable finish, such as tool grips, shoe soles, and protective cases.
• Medical Device Components: Suitable for non-implantable medical parts where biocompatibility, clarity, and sterilization resistance are needed (subject to specific grade validation).

Quality Control

Our thermoplastic polyurethane is manufactured under a stringent quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance, melt flow, and mechanical properties. Key parameters such as hardness, tensile strength, elongation, and hydrolytic stability are verified. Certificates of Analysis (COA) detailing lot-specific results are provided with every shipment to support your quality assurance and regulatory 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 (typically 15-25°C). This material is hygroscopic (moisture-sensitive); original packaging should be kept sealed until use to prevent moisture absorption, which can affect processing and final properties. Keep away from strong acids, bases, and oxidizing agents.
