Description

1,6-Hexanediol Polymer With 1,6-Diisocyanatohexane And α-Hydro-ω-Hydroxypoly(Oxy-1,4-Butanediyl) is a specialized polyurethane prepolymer or thermoplastic polyurethane (TPU) elastomer, synthesized from key monomers including 1,6-hexanediol, 1,6-diisocyanatohexane (HDI), and a poly(tetramethylene ether) glycol (PTMEG) segment. This engineered polymer is valued for its excellent mechanical properties, chemical resistance, and versatile processing characteristics. It is primarily utilized in industries requiring high-performance elastomers, such as automotive components, industrial hoses and belts, and advanced coatings and adhesives.

Application

• High-Performance Elastomers: Used in the manufacture of durable seals, gaskets, and vibration-damping components for automotive and machinery.
• Industrial Hose & Belt Manufacturing: Serves as a key material for hoses, conveyor belts, and drive belts requiring oil, abrasion, and hydrolysis resistance.
• Specialty Adhesives & Sealants: Acts as a base polymer for formulating high-strength, flexible adhesives and sealants used in construction and assembly.
• Protective & Functional Coatings: Employed in coatings for textiles, wires, cables, and industrial floors to provide toughness and chemical protection.
• Medical Device Components: Suitable for non-implantable medical tubing and device parts where biocompatibility and flexibility are required.
• Consumer Goods: Found in high-wear applications such as shoe soles, sporting goods, and protective cases.

Quality Control

Our polyurethane polymers are manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through comprehensive testing of key parameters including NCO content, viscosity, molecular weight distribution, and mechanical properties. Certificates of Analysis (COA) detailing all specifications are provided with each shipment. Production can adhere to relevant ISO quality management 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 room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Store away from incompatible materials such as strong acids, bases, and oxidizing agents.
