Description

1,4-Butanediol, Polymer With 1,1-Methylenebis4-Isocyanatobenzene, Methyloxirane And 1,2-Propanediol is a specialized polyurethane prepolymer or polyol derivative, synthesized from key monomers including 1,4-butanediol (BDO), methylene diphenyl diisocyanate (MDI), propylene oxide, and propylene glycol. This compound matters as a high-performance building block, offering precise control over final polymer properties such as flexibility, hardness, and chemical resistance. It is primarily needed by manufacturers in the polyurethane industry for producing advanced elastomers, coatings, adhesives, and sealants, where tailored performance is critical.

Application

• Polyurethane Elastomers: A key intermediate for manufacturing high-performance cast, thermoplastic, and millable polyurethane elastomers used in industrial wheels, rollers, and seals.
• Coatings & Adhesives: Serves as a reactive component in formulating durable, chemical-resistant protective coatings, industrial paints, and high-strength adhesives.
• Sealants & Binders: Used in the production of flexible and rigid sealants, as well as binders for composite materials and foundry sands.
• Resin Modification: Acts as a modifier for other polymer systems to enhance impact resistance, flexibility, and adhesion properties.
• Specialty Foams: Employed in the synthesis of specialized microcellular foams and integral skin foams for technical applications.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. We maintain strict process controls to ensure batch-to-batch consistency in key parameters such as isocyanate (NCO) content, hydroxyl value, viscosity, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive (hygroscopic) and may react with atmospheric moisture; containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) when not in use. Keep away from heat, sparks, and open flame.
