Description

Poly(Ethylene Glycol) Behenyl Ether Methacrylate is a specialized, high-molecular-weight methacrylate monomer designed for creating polymers with unique surface-active and hydrophobic properties. This compound is valued for its ability to impart excellent lubricity, emulsification, and compatibility in demanding formulations. It is primarily sought by manufacturers in the personal care, coatings, and specialty polymer industries for developing advanced performance materials.

Application

• Personal Care & Cosmetics: A key ingredient in high-performance hair conditioners, skin creams, and sunscreens, where it acts as an emollient, thickener, and provides a smooth, non-greasy feel.
• Coatings & Inks: Used as a reactive monomer in UV-curable coatings, inks, and adhesives to enhance flexibility, adhesion, and surface wetting properties.
• Polymer Modification: Serves as a macromonomer for synthesizing comb-like or graft copolymers, improving the compatibility and processability of polymer blends.
• Lubricants & Release Agents: Incorporated into formulations for fiber lubricants and mold release agents due to its excellent lubricating characteristics.
• Textile Auxiliaries: Utilized in fabric softeners and finishing agents to provide a soft hand feel and durable water repellency.

Quality Control

Our Poly(Ethylene Glycol) Behenyl Ether Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Key parameters such as assay, residual monomer content, and ethylene oxide distribution are monitored. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your specifications.

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). Keep away from heat sources and incompatible materials such as strong oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent polymerization and maintain product integrity.
