Description

Oxirane, Methyl-, Polymer With 2,4-Diisocyanato-1-Methylbenzene And Oxirane is a specialized polyurethane polyol prepolymer derived from propylene oxide and toluene diisocyanate (TDI). This compound matters as a versatile chemical intermediate, offering controlled reactivity and tailored properties for advanced polymer synthesis. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing rigid and flexible polyurethane foams.

Application

• Polyurethane Coatings: Serves as a key polyol component in high-performance protective and decorative coatings for industrial and automotive applications.
• Adhesives & Sealants: Used in formulating polyurethane-based adhesives and sealants that require excellent adhesion, flexibility, and chemical resistance.
• Elastomers: Acts as a prepolymer for manufacturing castable and thermoplastic polyurethane elastomers used in wheels, gaskets, and industrial parts.
• Rigid & Flexible Foams: A crucial intermediate in the production of both rigid insulation foams and flexible cushioning foams.
• Composite Materials: Employed as a matrix resin or modifier in fiber-reinforced composites to enhance mechanical properties.
• Binder Systems: Utilized in foundry sands, abrasive tools, and other composite systems as a polymeric binder.

Quality Control

Our Oxirane, Methyl-, Polymer With 2,4-Diisocyanato-1-Methylbenzene And Oxirane is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in parameters such as hydroxyl value, isocyanate content, viscosity, and moisture. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
