The application scope of ethylene glycol dimethacrylate (EGDMA) continues to expand, but there are few market participants in my country

Ethylene glycol dimethacrylate (EGDMA), also known as ethylene glycol dimethacrylate, has a chemical formula of C10H14O4 and is an organic compound. EGDMA appears as a colorless and transparent liquid with no special smell. It is soluble in some organic solvents and insoluble in water. EGDMA has the advantages of heat resistance, leveling, dilution and good adhesion, and is widely used in medical and health, engineering plastics, synthetic rubber and other fields.

EGDMA preparation methods include transesterification, direct esterification and acid chloride alcohololysis. The transesterification method refers to the reaction of methyl methacrylate and ethylene glycol under the catalytic action of an alkaline catalyst to obtain a finished product. This method is the mainstream preparation method of EGDMA; the direct esterification method refers to the reaction of methyl methacrylate and ethylene glycol under the catalytic action of an alkaline catalyst. Under the action of agent and polymerization inhibitor, ethylene glycol and methacrylic acid are fully reacted, and finally the finished product is obtained through decompression and distillation; the acyl chloride alcoholysis method refers to reacting acrylic acid chloride and ethylene glycol at normal temperature and pressure to obtain the finished product. , this method can easily cause environmental pollution and has not yet been applied on a large scale.

According to the “2023-2028 China Ethylene Glycol Dimethacrylate (EGDMA) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center >》shows that EGDMA has excellent performance and is widely used in medical and health, engineering plastics, synthetic rubber and other fields. In the field of medical and health care, EGDMA can be used as a raw material for dentures, dental bridges and soft hydrophilic contact lenses; in the field of engineering plastics, EGDMA can be used as a cross-linking agent to modify plastics; in the field of synthetic rubber, EGDMA can be used to produce three-dimensional EPDM rubber. As the development of downstream industries accelerates, the market demand for EGDMA is becoming increasingly strong.

In recent years, with the in-depth research and technological progress, the application scope of EGDMA has been continuously expanded. In April 2023, a scientific research team from Shanghai University successfully prepared a new ionic liquid blended polymer electrolyte using EGDMA, ethyl acrylate (EA) and vinylene carbonate (VC) as polymer frameworks. This product can effectively improve battery performance The cycle performance is expected to be widely used in the field of energy storage in the future.

Major global EGDMA suppliers include Evonik of Germany, BASF of Germany, Mitsubishi Rayon of Japan, KPX Chemical Co., Ltd. of South Korea, TBK Company of South Korea, and Dow Chemical Company of the United States. )wait. Compared with overseas developed countries, my country’s EGDMA market has fewer participants. The main suppliers include Jinan Guohua Chemical Co., Ltd., Shandong Dongwu Chemical Co., Ltd., Shanghai Hechuang Chemical Co., Ltd., Yurui (Shanghai) Chemical Co., Ltd., etc. .

Industry analysts said that EGDMA has heat resistance and leveling properties and has broad applications in many fields such as medical and health care and engineering plastics. prospect. Due to factors such as high technical barriers, there are few participants in my country’s EGDMA market, and overseas companies dominate the market. In the future, as the technological innovation level of local enterprises continues to improve, my country’s high-performance EGDMA market share will increase.
