Description

Poly[Oxy(Methyl-1,2-Ethanediyl)], .Alpha.-Hydro-.Omega.-Hydroxy-, Polymer With 1,3-Diisocyanato-2-Methylbenzene And 2,4-Diisocyanato-1-Methylbenzene is a high-performance polyurethane prepolymer derived from a polyether polyol and a mixture of toluene diisocyanate (TDI) isomers. This specialized chemical is engineered to deliver superior reactivity, controlled molecular weight, and tailored physical properties for demanding industrial formulations. It is a critical raw material for manufacturers in the adhesives, sealants, coatings, and elastomers industries seeking to enhance product durability and performance.

Application

• High-Performance Polyurethane Adhesives & Sealants: Serves as a key prepolymer component for one- and two-part systems requiring excellent adhesion, flexibility, and chemical resistance.
• Elastomer and Castable Urethane Production: Used in the manufacture of industrial rollers, wheels, gaskets, and impact-absorbing components.
• Protective & Decorative Coatings: Formulated into durable coatings for industrial flooring, automotive underbody protection, and marine applications.
• Binder Systems for Composites: Acts as a matrix resin in composite materials, offering a balance of toughness and processability.
• Footwear and Apparel Components: Utilized in the production of midsoles, outsoles, and other polyurethane foam or solid parts.
• Automotive Parts Manufacturing: Found in interior components, sound dampening materials, and vibration isolation mounts.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, and moisture levels are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at temperatures recommended on the specific product label or technical data sheet (typically 15-25°C). Containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction.
