Description

Ethylene Dimethacrylate is a high-purity, difunctional methacrylate monomer essential for creating highly cross-linked polymer networks. Its primary value lies in its ability to form durable, chemically resistant, and transparent materials with excellent dimensional stability. This versatile crosslinker is a critical raw material for manufacturers in the dental materials, optical lens, adhesive, and specialty coating industries, where performance and reliability are paramount.

Application

• Dental Composites & Prosthetics: A key crosslinking agent in restorative resins, crown & bridge materials, and denture bases, providing strength, wear resistance, and low shrinkage.
• Optical Lenses & Fiber Optics: Used in the production of high-refractive-index, scratch-resistant eyeglass lenses and polymer optical fibers (POF).
• Industrial & UV-Curable Coatings: Imparts hardness, chemical resistance, and fast cure times in coatings for electronics, flooring, and automotive applications.
• Acrylic Sheet & Casting Resins: Serves as a crosslinker to enhance the heat resistance and surface hardness of cast polymethyl methacrylate (PMMA) sheets and molding compounds.
• Adhesives & Sealants: Improves cohesive strength, thermal stability, and environmental resistance in anaerobic and structural acrylic adhesives.
• Printing Plates & Photopolymers: A critical component in photopolymerizable resins for flexographic printing plates and 3D printing (stereolithography).
• Ion-Exchange Resins & Chromatography Media: Used as a crosslinker in the synthesis of macroporous polymeric beads for water treatment and separation sciences.

Quality Control

Our Ethylene Dimethacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, inhibitor content, and impurity profiles are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat, sparks, open flames, and strong oxidizing agents. For long-term storage, maintain under an inert atmosphere (e.g., nitrogen) to prevent premature polymerization.
