Description

Poly(oxy-1,4-butanediyl), .alpha.-hydro-.omega.-hydroxy-, polymer with 1,3-diisocyanato-2-methylbenzene and 2,4-diisocyanato-1-methylbenzene is a specialized polyurethane prepolymer or polyether-based polyol derivative. This compound is a critical intermediate for synthesizing high-performance polyurethane elastomers, coatings, and adhesives with tailored properties. It is essential for manufacturers in the automotive, construction, and industrial coatings sectors seeking to enhance product durability, flexibility, and chemical resistance.

Application

• Polyurethane Elastomer Production: A key reactive component for manufacturing castable, thermoplastic, and millable polyurethane elastomers used in industrial wheels, seals, and gaskets.
• High-Performance Coatings & Adhesives: Serves as a building block for formulating durable, chemical-resistant protective coatings, sealants, and structural adhesives.
• Automotive Components: Used in the production of under-the-hood parts, suspension bushings, and interior trim requiring excellent mechanical and thermal properties.
• Industrial Rollers & Linings: Essential for creating abrasion-resistant and solvent-resistant linings for pipes, tanks, and industrial rollers.
• Footwear & Sporting Goods: Provides the material basis for soles, midsoles, and other components demanding high resilience and wear resistance.
• Fiber & Fabric Treatment: Used in coatings and finishes to impart water repellency, durability, and flexibility to technical textiles.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, and hydroxyl value are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This material is hygroscopic (moisture-sensitive). Ensure containers are sealed immediately after use to prevent moisture absorption, which can affect product performance. Keep away from heat, sparks, and open flame.
