Description

Poly(Ethylene Glycol) Diacrylate is a versatile bifunctional monomer featuring reactive acrylate groups at both ends of a poly(ethylene glycol) chain. This structure is critical for creating cross-linked polymer networks with tailored hydrophilicity, flexibility, and biocompatibility. It is an essential raw material for manufacturers in the photopolymer, biomedical, and advanced materials sectors seeking to develop innovative, high-performance products.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent in formulations for wood, plastic, and metal coatings, as well as printing inks, enabling rapid curing and enhanced durability.
• Hydrogel Synthesis: Serves as a primary monomer for creating hydrophilic hydrogels used in wound dressings, contact lenses, and drug delivery systems.
• Photoresists & 3D Printing Resins: Used in stereolithography (SLA) and digital light processing (DLP) resins to produce precise, water-compatible parts and microfluidic devices.
• Adhesives & Sealants: Imparts flexibility and adhesion in radiation-curable adhesive formulations for electronics and medical device assembly.
• Biomedical Research: Employed to fabricate synthetic extracellular matrices and scaffolds for tissue engineering applications.
• Superabsorbent Polymers (SAPs): A component in the production of polymers designed for high water absorption capacity.

Quality Control

Our Poly(Ethylene Glycol) Diacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC, determination of acid value, and measurement of water content, to ensure consistent purity and performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. To prevent premature polymerization, it is recommended to store under an inert atmosphere and away from heat and polymerization initiators.
