Uses of Ethylene dimethacrylate:
This product is a cross-linking agent used to prepare resins, coatings and adhesives. A raw material for preparing cancer drugs.
Ethylene glycol dimethacrylate is mainly used in the plastics and rubber industries, as ethylene-acrylic acid copolymer, ABS, acrylic sheet, pipe, glass fiber reinforced polyester, PVC, ion exchange resin, smokeless powder package polymerization, Crosslinking agents such as glazing have their copolymerized polymers, which increase hardness, improve heat resistance, weather resistance, solvent resistance and friction. In addition, they are also used in artificial marble, dental materials, emulsion copolymers, papermaking, and rubber peroxidation. Modifiers, adhesives, inks, crosslinking agents for optical polymers.
Production method of Ethylene dimethacrylate:
Direct esterification of ethylene glycol and methacrylic acid under sulfuric acid catalysis, and the crude product obtained is finished after vacuum distillation.
