Description

Polyglycerol Methacrylate is a versatile, multifunctional monomer derived from renewable glycerol. This compound matters for its unique ability to introduce both hydrophilic polyglycerol chains and polymerizable methacrylate groups, enabling the synthesis of advanced materials with tailored properties. Industries such as personal care, biomedical engineering, and specialty coatings need it to create biocompatible hydrogels, moisture-retentive polymers, and high-performance surface modifiers.

Application

• Biomedical Hydrogels & Contact Lens Materials: Serves as a key monomer for synthesizing soft, oxygen-permeable, and biocompatible polymer networks.
• Personal Care & Cosmetic Formulations: Used in hair styling resins, skin care products, and makeup for its film-forming and moisturizing properties.
• Drug Delivery Systems: Employed to create controlled-release matrices and nanoparticles due to its hydrophilic and modifiable structure.
• Adhesives & Sealants: Imparts flexibility, adhesion, and moisture resistance in specialty adhesive formulations.
• Coatings & Inks: Acts as a reactive diluent or modifier in UV-curable coatings and printing inks to enhance flexibility and substrate adhesion.
• Dental Materials: A component in restorative resins and dental adhesives for improved durability and biocompatibility.

Quality Control

Our Polyglycerol Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, functionality, and performance. Key parameters such as degree of polymerization, methacrylate content, and residual monomers are controlled. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen). Keep away from heat sources and incompatible materials.
