Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,1-Methylenebis4-Isocyanatobenzene And 1,2-Propanediol CAS NO 34229-60-2 is a high-performance thermoplastic polyurethane (TPU) elastomer, synthesized from adipic acid (hexanedioic acid), butanediol, MDI (diphenylmethane diisocyanate), and propylene glycol. This engineered polymer is valued for its exceptional balance of mechanical strength, elasticity, chemical resistance, and processability, making it a versatile material for demanding applications. It is primarily utilized in industries such as automotive manufacturing, industrial machinery, consumer goods, and specialized coatings where durable, flexible components are required.

Application

• Automotive Components: Used in the production of durable seals, gaskets, cable jacketing, and interior trim parts due to its abrasion resistance and flexibility across a wide temperature range.
• Industrial Hose and Tubing: Serves as a key material for flexible hoses, pneumatic tubes, and hydraulic lines that require resilience to oils, greases, and mechanical stress.
• Consumer Goods and Footwear: Employed in the manufacture of shoe soles, watch straps, phone cases, and sporting goods for its comfort, durability, and aesthetic finish.
• Technical Molding: Ideal for injection molding and extrusion of complex, high-performance parts like rollers, wheels, and seals in machinery.
• Wire and Cable Insulation: Provides excellent insulating properties and protection for electrical cables in demanding environments.
• Adhesives and Sealants: Acts as a base polymer in formulating high-strength, flexible adhesives and sealants for construction and assembly.
• Protective Coatings: Used in coatings for textiles, industrial fabrics, and flooring to impart waterproofing, abrasion resistance, and longevity.
• Medical Device Components: Suitable for non-implantable medical device parts requiring biocompatibility, clarity, and sterilization resistance in specific grades.

Quality Control

Our thermoplastic polyurethane is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Quality is verified through comprehensive testing of key parameters including melt flow index, hardness (Shore A/D), tensile strength, elongation at break, and chemical resistance. We provide full traceability and Certificates of Analysis (COA) with each shipment, detailing the specific properties of your order. Our production can align with relevant industry standards for specific applications.

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 containers are sealed after use to prevent moisture absorption, which can affect processing properties.
