Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,6-Hexanediol And 1,1-Methylenebis4-Isocyanatobenzene is a high-performance thermoplastic polyurethane (TPU) elastomer, known for its excellent balance of mechanical properties and chemical resistance. This engineered polymer is crucial for applications demanding durability, flexibility, and resilience under challenging environmental conditions. It is primarily sought after by manufacturers in the automotive, industrial machinery, and specialized consumer goods sectors for producing seals, gaskets, hoses, and durable molded components.

Application

• Automotive Components: Used in the manufacture of durable seals, gaskets, bushings, and under-the-hood hoses that require oil and fuel resistance.
• Industrial Machinery Parts: Ideal for producing wear-resistant rollers, belts, and linings that can withstand abrasion and mechanical stress.
• Consumer Goods: Employed in high-performance footwear soles, sports equipment, and protective cases where flexibility and toughness are key.
• Wire and Cable Jacketing: Serves as a protective, flexible, and durable outer sheath for cables requiring good mechanical and environmental protection.
• Medical Device Components: Suitable for non-implantable medical tubing and device parts that benefit from its clarity, flexibility, and biocompatibility in certain grades.
• Hydraulic and Pneumatic Seals: Formulated into seals and diaphragms that perform reliably under pressure and in contact with various fluids.

Quality Control

Our thermoplastic polyurethane is produced under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hardness, tensile strength, elongation, and melt flow index are rigorously tested. Certificates of Analysis (COA) detailing specific lot properties are available upon request. Production can adhere to relevant industry standards based on application needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C). Original packaging should be kept sealed until use to prevent moisture absorption, which can affect processing and final properties. Store away from heat sources and open flames.
