Description

Poly[Oxy(Methyl-1,2-Ethanediyl)], .Alpha.,.Alpha.',.Alpha.''-1,2,3-Propanetriyltris[.Omega.-Hydroxy-, Polymer With 1,1'-Methylenebis[4-Isocyanatobenzene] is a specialized polyether-polyurethane copolymer, synthesized from a triol and MDI (methylene diphenyl diisocyanate). This engineered polymer is valued for its tailored reactivity and structural properties, making it a critical intermediate in advanced material formulations. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-performance polyurethane systems.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component in formulating durable, chemical-resistant, and weatherable coatings for industrial, automotive, and marine applications.
• Adhesives and Sealants: Used as a building block in reactive hot-melt adhesives (HMPUR) and high-strength structural sealants, offering excellent adhesion and flexibility.
• Elastomer Production: A precursor for casting or thermoplastic polyurethane (TPU) elastomers used in wheels, gaskets, and industrial belts.
• Composite Materials: Functions as a matrix resin or modifier in fiber-reinforced composites, enhancing toughness and interfacial bonding.
• Flexible Foams: Can be utilized in the formulation of specialized, high-resilience flexible polyurethane foams.
• Binder Systems: Acts as a polymeric binder in advanced foundry sands, abrasives, and non-woven materials.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is controlled against strict specifications for parameters such as NCO content, hydroxyl value, viscosity, and moisture content to guarantee batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these results are available upon request.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture absorption, which can affect reactivity and properties.
