Description

1,4-Butanediol, Polymer With 1,3-Diisocyanatomethylbenzene, α-Hydro-ω-Hydroxypoly( Oxy-1,4-Butanediyl) And α-Hydro-ω-Hydroxypoly( Oxy-1,2-Ethanediyl) is a specialized polyurethane prepolymer or block copolymer designed for high-performance applications. This engineered material is valued for its unique combination of properties derived from its segmented structure, offering tailored flexibility, toughness, and chemical resistance. It is primarily sought by formulators and manufacturers in the adhesives, sealants, coatings, and elastomers industries for creating durable, resilient end-products.

Application

• High-Performance Polyurethane Adhesives & Sealants: Acts as a key prepolymer component for formulating flexible, moisture-curing adhesives with excellent bond strength and durability.
• Elastomer and Coating Systems: Used in the synthesis of castable or sprayable polyurethane elastomers and protective coatings that require a balance of hardness and elasticity.
• Thermoplastic Polyurethane (TPU) Modification: Serves as a chain extender or modifier to enhance the physical properties, such as abrasion resistance and low-temperature flexibility, of TPU compounds.
• Industrial and Composite Binders: Employed in binder systems for composites, foundry sands, and other industrial materials where strong, flexible matrices are critical.
• Specialty Resin Intermediates: Functions as a reactive intermediate for further chemical synthesis into more complex polymer systems with customized performance profiles.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters monitored include NCO content, viscosity, hydroxyl value, and moisture content. Certificates of Analysis (COA) detailing these specifications are available upon request. Our manufacturing processes adhere to ISO 9001 quality management principles to guarantee reliability for your formulations.

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); ensure containers are sealed immediately after use to prevent moisture absorption and premature reaction. Keep away from heat, sparks, and open flame.
