Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,1-Methylenebis4-Isocyanatobenzene And 2,2-1,4-Phenylenebis(Oxy)Bisethanol CAS NO 32238-28-1 is a high-performance thermoplastic polyurethane (TPU) elastomer, engineered for demanding applications requiring a balance of flexibility, durability, and chemical resistance. This specialized polymer is valued for its excellent mechanical properties, including high tensile strength, abrasion resistance, and resilience across a wide temperature range. It is a critical material for manufacturers in the automotive, industrial machinery, and advanced consumer goods sectors seeking reliable elastomeric components.

Application

• Automotive Components: Used in the production of durable seals, gaskets, hoses, and cable sheathing that must withstand oils, fuels, and environmental stress.
• Industrial Rollers & Wheels: Formulated for high-abrasion resistance, making it ideal for conveyor system rollers, industrial casters, and drive wheels.
• Hydraulic & Pneumatic Seals: Provides reliable performance in dynamic sealing applications due to its excellent compression set and fluid resistance.
• Consumer Electronics: Employed in protective cases, cable insulation, and flexible connectors where a combination of toughness and aesthetic finish is required.
• Medical Device Tubing & Components: Suitable for non-implantable medical applications requiring biocompatibility, flexibility, and sterilization resistance.
• Sporting Goods: Used in high-performance footwear soles, protective gear, and equipment components that demand elasticity and long-term wear.
• Wire & Cable Jacketing: Offers superior protection against mechanical damage, chemicals, and weathering for specialized cables.
• Technical Molding: A preferred material for injection molding and extrusion of complex, high-strength technical parts.

Quality Control

Our thermoplastic polyurethane is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as hardness (Shore A/D), tensile strength, elongation at break, and melt flow index are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing physical, mechanical, and rheological properties is provided with every shipment to support your quality assurance protocols.

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 strong oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure original packaging is sealed after use to prevent moisture absorption, which can affect processing characteristics.
