Description

Poly(Ethylene Glycol) (N) Diglycidyl Ether is a versatile, reactive epoxy-functionalized polymer used as a crosslinking agent and modifier in advanced material synthesis. Its bifunctional epoxide groups and hydrophilic polyether backbone make it a critical component for creating tailored polymers with specific mechanical and chemical properties. This product is essential for formulators and researchers in the adhesives, coatings, composites, and biomedical sectors seeking to enhance flexibility, hydrophilicity, and reactivity in their systems.

Application

• Epoxy Resin Modification: Used as a reactive diluent and flexibilizer to reduce viscosity and improve impact resistance in epoxy adhesives and coatings.
• Crosslinking Agent for Polymers: Serves as a hydrophilic crosslinker in the synthesis of hydrogels for biomedical applications, including drug delivery systems and contact lenses.
• Surface Coatings: Incorporated into formulations for durable, hydrophilic surface coatings on textiles, membranes, and medical devices.
• Composite Materials: Acts as a coupling agent and matrix modifier in fiber-reinforced composites to improve interfacial adhesion and toughness.
• Chemical Intermediate: Utilized in organic synthesis to introduce polyether chains and reactive epoxide sites into specialty chemicals and pharmaceuticals.
• Adhesive Formulations: Enhances the flexibility and adhesion properties of structural and pressure-sensitive adhesives.

Quality Control

Our Poly(Ethylene Glycol) (N) Diglycidyl Ether is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent epoxy equivalent weight (EEW), purity, viscosity, and moisture content, meeting the specifications required for high-performance applications. Certificates of Analysis (COA) documenting these parameters are available upon request 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 product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect reactivity and product performance.
