Description

1,2-Ethanediol, Polymer With 1,3-Diisocyanatomethylbenzene Toluene Diisocyanate, Ethylene Glycol Polymer is a specialized polyurethane prepolymer or polyol derivative, synthesized from ethylene glycol and toluene diisocyanate (TDI). This compound is valued for its role as a key reactive intermediate, providing controlled molecular weight and functionality for advanced polymer synthesis. It is essential for industrial manufacturers seeking to produce tailored polyurethane systems with specific mechanical, thermal, or processing properties.

Application

• Polyurethane Elastomers: Serves as a chain extender or prepolymer component for manufacturing high-performance elastomers used in industrial wheels, seals, and gaskets.
• Coatings and Adhesives: Used in formulating specialty polyurethane coatings, lacquers, and adhesives that require enhanced flexibility, chemical resistance, and durability.
• Flexible and Rigid Foams: Acts as a modifying polyol to fine-tune the density, resilience, and load-bearing properties of polyurethane foam products.
• Sealants and Binders: A critical raw material in the production of high-grade construction sealants, composite binders, and encapsulants.
• Automotive Components: Utilized in the synthesis of polyurethane parts for automotive interiors, under-the-hood components, and vibration dampening materials.
• Textile and Leather Finishing: Employed in coatings and finishes to impart water resistance, abrasion resistance, and a soft hand feel to fabrics and synthetic leather.

Quality Control

Our production of this polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, hydroxyl value, viscosity, and molecular weight distribution are rigorously monitored. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 material is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
