Description

1,4-Butanediol-Diphenylmethane 4,4'-Diisocyanate-Polyethylene Adipate Glycol Copolymer is a specialized thermoplastic polyurethane (TPU) elastomer prepolymer based on MDI (4,4'-diphenylmethane diisocyanate). This high-performance material is engineered to deliver a unique balance of flexibility, durability, and chemical resistance, making it a critical raw material for advanced polymer formulations. It is primarily sought by manufacturers in the polyurethane, specialty adhesives, coatings, and elastomer industries for producing high-grade finished products.

Application

• Thermoplastic Polyurethane (TPU) Production: Serves as a key prepolymer for manufacturing high-performance TPU granules used in injection molding and extrusion.
• High-Performance Elastomers: Used in the formulation of castable and millable polyurethane elastomers for industrial rollers, seals, and gaskets requiring excellent mechanical properties.
• Specialty Adhesives & Sealants: A vital component in formulating reactive hot-melt and moisture-curing polyurethane adhesives with strong bonding and flexibility.
• Protective & Functional Coatings: Imparts toughness, abrasion resistance, and chemical resistance to industrial and protective coatings for metals, concrete, and textiles.
• Wire & Cable Insulation/Jacketing: Used to create flexible, durable, and flame-retardant insulation materials.
• Automotive Components: Found in the production of under-the-hood parts, interior trim, and other components demanding durability and performance.
• Footwear & Sporting Goods: Used in the soles of high-performance footwear and in components for sporting equipment due to its resilience and wear resistance.

Quality Control

Our 1,4-Butanediol-Diphenylmethane 4,4'-Diisocyanate-Polyethylene Adipate Glycol Copolymer is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of NCO content, viscosity, and mechanical properties of cured samples. Certificates of Analysis (COA) detailing key specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This material is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to atmospheric moisture or light can lead to polymerization, gelation, or degradation of product quality. Keep away from heat, sparks, and open flame.
