What is Ethylene dimethacrylate？

Ethylene dimethacrylate is a difunctional methacrylate monomer featuring two polymerizable methacryloyl groups. It exhibits high reactivity and serves as an excellent crosslinking agent in free radical polymerization systems. EDMA is widely used in the production of crosslinked polymers, dental materials, optical lenses, and chromatographic fillers due to its ability to form rigid, three-dimensional networks, enhancing the thermal stability, mechanical strength, and solvent resistance of the final products.

Application:

1.Dental Materials:

A key crosslinking agent in dental composites, denture bases, and restorative resins, providing hardness and wear resistance.

2.Optical Lenses:

Ethylene dimethacrylate used in the production of hard, transparent optical lenses and contact lenses.

3.Chromatographic Media:

Ethylene dimethacrylate serves as a crosslinker in the synthesis of polymer-based HPLC column fillers and solid-phase extraction adsorbents.

4.Coatings & Inks:

Imparts crosslinked structures to UV-curable coatings, inks, and adhesives, enhancing their durability and chemical resistance.

5.Polymer Modification:

Ethylene dimethacrylate used to modify the properties of acrylic, vinyl, and styrene polymers, improving their thermal and mechanical performance.

6.Biomedical Applications:

Ethylene dimethacrylate employed in the fabrication of hydrogels and drug delivery carriers .

Safety profile:

Ethylene dimethacrylate may cause skin and eye irritation, and skin sensitization. The monomer is typically stabilized with an inhibitor (e.g., MEHQ) to prevent spontaneous polymerization. Use with adequate ventilation and personal protective equipment (PPE), including gloves and safety goggles. Avoid exposure to heat, light, and peroxides which may initiate polymerization.

Storage requirements:

keep the product dry

relative humidity < 50%

protect product against influences of weather and contamination

Transport & Packaging:

Ethylene dimethacrylate MONO-TERT-BUTYL ETHERmay for technical applications is solely supplied in packaging of different sizes . It can be packaged in various items: 25 kg drums, 1000 kg IBC drums.
