Description

Hexanedioic Acid,Polymer With 1,2-Ethanediol,2,2,-Oxybis(Ethanol) And 1,1,-Methylenebis(4-Isocyanatobenzene) is a specialized polyurethane prepolymer or resin intermediate, synthesized from adipic acid, glycols, and MDI. This engineered polymer is valued for its ability to impart tailored flexibility, toughness, and chemical resistance to final polyurethane systems. It is primarily required by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials.

Application

• High-Performance Polyurethane Coatings: Used as a key resin component in protective and decorative coatings for automotive, industrial, and marine applications, offering excellent durability and gloss retention.
• Adhesives and Sealants: Serves as a base polymer for formulating strong, flexible structural adhesives and moisture-curing sealants with good adhesion to various substrates.
• Elastomer Production: Acts as a prepolymer for casting or molding polyurethane elastomers used in wheels, rollers, gaskets, and impact-absorbing components.
• Composite Materials: Employed as a matrix resin in fiber-reinforced composites for the automotive and aerospace sectors, contributing to lightweight and strong parts.
• Flexible Foams and Cushioning: Can be utilized in the formulation of specialized, high-resilience flexible polyurethane foams.
• Industrial Binders and Encapsulants: Used in potting compounds and binders for electrical components or abrasive grains, providing insulation and structural integrity.

Quality Control

Our production of this polyurethane intermediate adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, hydroxyl value, and acid number to ensure consistency and performance in downstream formulations. Comprehensive Certificates of Analysis (COA) documenting these specifications are provided with every shipment.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for the specific grade (typically between 15°C and 25°C). This material is moisture-sensitive; exposure to atmospheric humidity will cause premature curing. Keep away from heat sources and open flames.
