Description

Poly(Ethylene Glycol) Acrylate is a versatile reactive monomer featuring a polymerizable acrylate group and a hydrophilic poly(ethylene glycol) chain. This bifunctional structure is critical for creating polymers with tailored hydrophilicity, flexibility, and biocompatibility. It is essential for manufacturers in the biomedical, personal care, and advanced materials sectors seeking to develop high-performance hydrogels, coatings, and functional polymers.

Application

• Hydrogel Synthesis: A key precursor for creating superabsorbent, biocompatible hydrogels used in wound dressings, contact lenses, and drug delivery systems.
• Surface Modification & Coatings: Used to graft hydrophilic, non-fouling PEG layers onto surfaces for medical devices, biosensors, and anti-fog coatings.
• UV/EB Curable Systems: Serves as a reactive diluent and crosslinker in radiation-curable inks, adhesives, and coatings, imparting flexibility and adhesion.
• Bioconjugation & Pharmaceutical: Employed in PEGylation chemistry to modify proteins, peptides, and drug molecules to enhance solubility and circulation time.
• Personal Care Products: Incorporated into formulations for hair styling gels, skin care products, and cosmetics to provide film-forming and moisturizing properties.
• Acrylic Resin Modification: Used to copolymerize with other acrylic monomers to produce resins with enhanced water solubility, toughness, and low shrinkage.

Quality Control

Our Poly(Ethylene Glycol) Acrylate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, molecular weight distribution, and performance. Certificates of Analysis (COA) detailing assay, impurity profile, and physical properties are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified for the specific grade to maximize shelf life and inhibit polymerization. This material is hygroscopic (moisture-sensitive); keep containers tightly sealed when not in use.
