Description

Hexanedioic Acid, Polymer With 1,4-Butanediol And 1,6-Diisocyanatohexane is a high-performance polyurethane prepolymer or thermoplastic polyurethane (TPU) elastomer, synthesized from adipic acid, 1,4-butanediol, and hexamethylene diisocyanate (HDI). This engineered polymer is valued for its excellent mechanical properties, including high tensile strength, elasticity, abrasion resistance, and good low-temperature flexibility. It is essential for manufacturers in the elastomers, adhesives, coatings, and specialty plastics industries seeking durable and versatile polymeric materials.

Application

• Thermoplastic Polyurethane (TPU) Elastomers: Used in the production of high-performance films, sheets, hoses, cables, and automotive parts.
• Adhesives and Sealants: Serves as a key component in formulating high-strength, flexible polyurethane adhesives for industrial bonding and construction sealants.
• Coatings and Paints: Imparts durability, chemical resistance, and flexibility to industrial and protective coatings for metals, textiles, and plastics.
• Synthetic Leather and Textile Finishing: Used in coatings for synthetic leather (PU leather) and as a textile finish to provide water resistance and enhanced feel.
• Footwear and Sporting Goods: A critical raw material for shoe soles, ski boots, and other items requiring a balance of flexibility and toughness.
• Medical Device Components: Employed in the manufacture of certain medical tubing and device parts where biocompatibility and performance are required.
• Industrial Rollers and Gaskets: Formulated into durable components that withstand continuous mechanical stress and environmental exposure.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, hydroxyl value, and molecular weight distribution are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific grade specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light and moisture. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
