Introduction | ethylene glycol dimethacrylate is a Diester, it means that there is a combination of two alcohols/acids in one organic compound or monomer. Industry often combines this substance with other chemicals to make plastics or rubber. Many manufacturers use ethylene glycol dimethacrylate, commonly known as EGDMA, from building materials to medical devices and laboratory research. |
Application | ethylene glycol dimethacrylate is generally non-irritating and toxic, and EGDMA can be used to make dental bridges and dentures. The plastics and rubber industry typically includes ethylene glycol dimethacrylate in the manufacture of fiberglass polyester, polyvinyl chloride pipes, and rubber tubing. This material is commonly used as one of the raw materials for the manufacture of acrylic sheets, plastics, and resins. Such compounds generally increase the hardness of these products, but also impart the ability to resist friction to the finished product. EGDMA also provides chemicals, heat, and, possibly, adhesives, emulsifiers, humectants, and plasticizers. EGDMA manufacturers typically add this compound to detergents and textile lubricants, the industry of paper-making or printing inks may also be used. |
purpose | This product is a cross-linking agent, which is used to prepare resins, coatings and adhesives. A raw material for the preparation of cancer drugs ethylene glycol dimethacrylate is mainly used in plastic and rubber industries, as ethylene-acrylic acid copolymer, ABS, acrylic sheet, pipe, glass fiber reinforced polyester, PVC, ion exchange resin, smokeless powder coating polymerization, glazing and other cross-linking agents, there are its participation in the copolymerization of polymers, increased hardness, heat resistance, weather resistance, solvent resistance and friction resistance to improve, in addition, it is also used in artificial marble, dental materials, emulsion copolymers, paper making, rubber peroxyl hardening modifiers, adhesives, inks, crosslinking agents for optical polymers. |
production method | ethylene glycol and methacrylic acid are directly esterified under sulfuric acid catalysis, and the obtained crude product is subjected to reduced pressure distillation and then finished. |
