Description

Poly(Ethylene Glycol) Dimethacrylate is a versatile, multi-functional monomer characterized by its reactive methacrylate end groups and a flexible poly(ethylene glycol) (PEG) chain. This structure makes it a crucial crosslinking agent and modifier for creating polymers with tailored hydrophilicity, flexibility, and biocompatibility. It is essential for formulators and manufacturers in industries such as medical devices, hydrogels, advanced coatings, and specialty adhesives seeking to enhance material performance.

Application

• Hydrogel Manufacturing: A key crosslinker for producing superabsorbent polymers, contact lenses, wound dressings, and drug delivery matrices.
• UV-Curable Systems: Used in inks, coatings, and adhesives that cure rapidly under UV light, offering excellent film flexibility and adhesion.
• Dental Composites & Restoratives: Imparts low shrinkage and improved mechanical properties in light-curable dental resins and sealants.
• Biomedical & Tissue Engineering: Serves as a building block for creating biocompatible and biodegradable polymer scaffolds.
• Personal Care Products: Employed in the synthesis of film-forming agents and delivery systems for cosmetics and skincare.
• Lithography & Photoresists: Acts as a monomer in photopolymer formulations for microelectronics and printing plates.
• Modifier for Acrylic Resins: Enhances the toughness, flexibility, and water resistance of acrylic-based polymers.

Quality Control

Our Poly(Ethylene Glycol) Dimethacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, functionality, and performance. Key parameters monitored include assay (monomer content), degree of ethoxylation, acid value, color, and water content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing the specific results for your quality assurance records.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its reactivity, store separately from strong acids, bases, and oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
