Description

Oxirane, Methyl-, Polymer With Oxirane, Ether With 1,2,3-Propanetriol (3:1), Polymer With 1,3-Diisocyanato-2-Methylbenzene And 2,4-Diisocyanato-1-Methylbenzene is a specialized polyurethane prepolymer derived from propylene oxide, glycerol, and a mixture of toluene diisocyanate (TDI) isomers. This compound matters as a versatile and reactive intermediate, providing the foundational chemistry for high-performance polyurethane systems. Industrial manufacturers in coatings, adhesives, sealants, and elastomers (CASE) rely on this consistent-quality prepolymer to develop products with tailored properties such as flexibility, chemical resistance, and durability.

Application

• Polyurethane Elastomers: As a key building block for casting, molding, and thermoplastic polyurethane (TPU) formulations requiring specific hardness and resilience.
• Industrial Coatings & Paints: Used in the synthesis of polyurethane resins for protective coatings, offering excellent abrasion resistance and weatherability.
• Adhesives & Sealants: Serves as a prepolymer in high-strength, flexible adhesive systems for construction, automotive, and composite bonding.
• Binder Systems: Employed in foundry sands, composite materials, and non-woven fabrics as a reactive polymeric binder.
• Footwear & Sporting Goods: A critical component in the production of midsoles, soles, and other molded polyurethane parts.
• Automotive Parts: Used in the manufacture of interior components, gaskets, and vibration-damping materials.
• Waterproofing Membranes: Formulated into liquid-applied membranes and coatings for roofing and infrastructure.

Quality Control

Our Oxirane, Methyl-, Polymer With Oxirane, Ether With 1,2,3-Propanetriol (3:1), Polymer With 1,3-Diisocyanato-2-Methylbenzene And 2,4-Diisocyanato-1-Methylbenzene is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent NCO content, viscosity, and hydroxyl value, meeting precise customer specifications. Certificates of Analysis (COA) documenting purity, key physical properties, and performance indicators are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for polyurethane prepolymers (typically 15-25°C). This product is moisture-sensitive (hygroscopic) and can be easily oxidized; containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen blanket) after opening to prevent moisture absorption and premature reaction.
