Description

1,4-Butanediol, Polymer With 1,3-Diisocyanatomethylbenzene And .Alpha.-Hydro-.Omega.-Hydroxypoly[Oxy(Methyl-1,2-Ethanediyl)] is a specialized polyurethane prepolymer or block copolymer, widely utilized as a high-performance raw material in advanced polymer synthesis. This compound is valued for its ability to impart tailored elastomeric properties, including flexibility, toughness, and chemical resistance, to the final polymeric matrix. It is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty polyurethane dispersions and thermoplastic polyurethanes.

Application

• High-Performance Polyurethane Elastomers: Used as a key building block for manufacturing elastomers requiring excellent mechanical strength, abrasion resistance, and dynamic performance.
• Coatings and Adhesives: Serves as a prepolymer in formulating durable, flexible, and chemical-resistant protective coatings, paints, and structural adhesives.
• Sealants and Caulks: Imparts long-term elasticity and adhesion in construction and industrial sealant applications.
• Thermoplastic Polyurethane (TPU) Production: A critical intermediate in the synthesis of TPUs used in films, cables, hoses, and consumer goods.
• Polyurethane Dispersions (PUDs): Acts as a core component for creating water-based PUDs for eco-friendly coatings and finishes.
• Composite Materials: Used to modify and enhance the properties of polymer composites for automotive and aerospace components.
• Specialty Resins and Binders: Employed in the formulation of advanced binders for industrial and electronic applications.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, viscosity, and molecular weight distribution are rigorously monitored. Certificates of Analysis (COA) detailing specific lot specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under dry, inert conditions (e.g., under dry nitrogen) to prevent premature reaction and degradation. Recommended storage temperature is between 15°C and 25°C in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as alcohols, amines, and moisture.
