Description

Methyl oxirane polymer with oxirane, ether with 1,2,3-propanetriol(3:1) polymer with α-hydro-ω-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1′-methylenebis(isocyanatobenzene) is a specialized polyurethane prepolymer or polyol derivative, synthesized from a complex polyether polyol and methylene diphenyl diisocyanate (MDI). This compound matters as a high-performance reactive intermediate designed to impart tailored flexibility, adhesion, and chemical resistance in advanced polymer systems. Industrial manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) sectors require it for formulating durable, cross-linked polyurethane products with specific mechanical and thermal properties. Its precise structure allows for customization in demanding applications where standard polyols are insufficient.

Application

• High-Performance Polyurethane Coatings: Used as a key resin component in protective coatings for industrial flooring, marine applications, and automotive finishes, offering enhanced weatherability and chemical resistance.
• Structural Adhesives and Sealants: Serves as a backbone polymer in formulations requiring strong, flexible bonds and long-term durability in construction and automotive assembly.
• Cast and Thermoplastic Polyurethane Elastomers (TPU): Acts as a prepolymer for manufacturing flexible parts, gaskets, wheels, and industrial belts that demand a balance of toughness and elasticity.
• Composite Materials: Incorporated as a matrix resin or modifier in fiber-reinforced plastics (FRP) to improve impact resistance and interfacial adhesion.
• Specialty Binders and Encapsulants: Utilized in electronic potting compounds and industrial binder systems where moisture resistance and dimensional stability are critical.
• Footwear and Sporting Goods: A component in the production of midsoles, outsoles, and other molded polyurethane components that require specific cushioning and wear properties.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Every batch is characterized for critical parameters including isocyanate (NCO) content, viscosity, hydroxyl value, and moisture content to ensure consistent reactivity and performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing the specifications for your quality assurance needs. Our commitment to reliable supply and batch-to-batch consistency supports your formulation stability and production efficiency.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep containers tightly sealed under a dry inert atmosphere (e.g., nitrogen blanket) to prevent moisture absorption and premature reaction. Isolate from sources of heat, sparks, and open flame.
