Description

Poly(Ethylene Glycol) (N) Diglycidyl Ether is a versatile epoxy-functionalized polymer derivative, primarily used as a reactive diluent, crosslinking agent, or hydrophilic modifier in advanced polymer formulations. Its bifunctional glycidyl ether structure provides excellent compatibility and reactivity, enabling the synthesis of tailored materials with specific mechanical and surface properties. This product is essential for manufacturers in the coatings, adhesives, composites, and biomedical sectors seeking to enhance flexibility, hydrophilicity, and chemical resistance in their end products.

Application

• As a reactive diluent and flexibilizer in epoxy resin systems for coatings, adhesives, and sealants.
• As a crosslinking agent in the production of hydrophilic gels, hydrogels, and controlled-release matrices for pharmaceutical and biomedical applications.
• As a chemical intermediate for the synthesis of specialty surfactants and surface modifiers.
• In the formulation of composite materials to improve interfacial adhesion and toughness.
• For the modification of textiles and fibers to impart durable hydrophilic characteristics.
• In research and development for creating functional polymers with tailored chain length and reactivity.

Quality Control

Our Poly(Ethylene Glycol) (N) Diglycidyl Ether is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in epoxy equivalent weight (EEW), viscosity, and purity. Certificates of Analysis (COA) documenting key specifications are available for every shipment. We are committed to meeting the quality standards required for industrial and research applications.

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 product stability and reactivity.
