Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,4-Butanediyl) And 1,1'-Methylenebis[4-Isocyanatobenzene] CAS NO 70714-96-4 is a high-performance thermoplastic polyurethane (TPU) elastomer. This material is engineered to deliver an exceptional balance of mechanical strength, chemical resistance, and processing flexibility, making it a critical component in demanding industrial applications. It is primarily sought by manufacturers in the automotive, industrial machinery, and specialized consumer goods sectors for creating durable, resilient parts.

Application

• Automotive Components: Used in the production of seals, gaskets, hoses, and cable sheathing due to its excellent abrasion resistance and flexibility over a wide temperature range.
• Industrial Rollers and Wheels: Ideal for manufacturing high-load-bearing rollers, conveyor belt components, and industrial casters where durability and resistance to oils and greases are required.
• Technical Films and Sheets: Employed in creating protective films, diaphragms, and weather-resistant sheets that demand high tensile strength and tear resistance.
• Wire and Cable Insulation: Serves as a premium jacketing material for cables requiring superior mechanical protection, flexibility, and resistance to environmental stress cracking.
• Footwear and Sporting Goods: Utilized in the soles of high-performance footwear, ski boots, and other sporting equipment for its cushioning, wear resistance, and bondability.
• Medical Device Components: Applied in non-implantable medical tubing and device parts where biocompatibility grades are available, offering clarity, kink resistance, and sterilizability.
• Adhesives and Sealants: Acts as a key raw material in formulating high-strength, flexible polyurethane adhesives and sealants for construction and assembly.

Quality Control

Our thermoplastic polyurethane is manufactured under a strict quality management system. Each batch undergoes comprehensive testing for key parameters including intrinsic viscosity, hardness (Shore A/D), tensile strength, elongation at break, and hydrolytic stability to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can support compliance with relevant industry standards upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C/59-77°F). Keep the original packaging sealed until use to prevent moisture absorption, which can affect processing and final product properties.
