Description

Propanol, [(1-Methyl-1,2-Ethanediyl)Bis(Oxy)]Bis-, Polymer With 1,1'-Methylenebis[4-Isocyanatobenzene] is a specialized polyurethane prepolymer or polyol derivative, synthesized from propylene glycol and diphenylmethane diisocyanate (MDI). This compound is valued for its role as a key reactive intermediate, providing controlled molecular weight and functionality for advanced polymer synthesis. It is essential for industrial manufacturers requiring precise chemical building blocks to develop high-performance polyurethane elastomers, coatings, and adhesives.

Application

• Polyurethane Elastomer Production: Serves as a crucial prepolymer or chain extender for manufacturing high-resilience, durable elastomers used in industrial wheels, seals, and gaskets.
• Specialty Coatings and Adhesives: Used as a reactive component in formulating high-performance, chemically resistant coatings, sealants, and structural adhesives.
• Composite Materials: Acts as a modifier or cross-linking agent in fiber-reinforced plastics and composite matrices to enhance mechanical properties.
• Automotive and Aerospace Components: Employed in the production of lightweight, strong polyurethane parts for interior and under-the-hood applications.
• Footwear and Sporting Goods: Utilized in the synthesis of polyurethane midsoles, soles, and other components requiring a balance of flexibility and toughness.
• Industrial Rollers and Linings: A key ingredient for creating abrasion-resistant and solvent-resistant polyurethane linings for pipes, tanks, and industrial rollers.

Quality Control

Our production of this polyurethane intermediate adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance. Key parameters such as NCO content, hydroxyl value, viscosity, and moisture content are strictly monitored. Certificates of Analysis (COA) documenting these specifications 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). Keep the container tightly sealed under a dry, inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Isolate from strong acids, bases, and other reactive chemicals.
