The concentration of propylene glycol methyl ether acetate industry is expected to continue to increase, and the future development prospects are broad.
Propylene glycol methyl ether acetate (PMA), also known as propylene glycol monomethyl ether acetate, is a non-pollution solvent with a molecular formula of C6H12O3 and multiple functional groups. Methyl malonate acetate appears as a colorless and transparent liquid with a special smell, high boiling point, and is flammable. It is a low-toxic advanced industrial solvent with excellent performance and is used in inks, coatings, paints, semiconductors, photolithography machines, textile dyes, etc. It is widely used in the field and is the best solvent in coatings and inks. It is suitable for epoxy resin, acrylic resin, unsaturated polyester, polyurethane resin and other products.
There are three main categories of production methods for propylene glycol methyl ether acetate, namely direct esterification method, transesterification method, and one-step synthesis method. Among them, the direct esterification method is currently the main method for industrial production of propylene glycol methyl ether acetate. It refers to the direct esterification method of using propylene glycol methyl ether and acetic acid as raw materials under the catalysis of concentrated sulfuric acid to obtain PMA. It has low production cost and relatively advanced technology. It has the advantages of being mature and producing better quality products.
In recent years, under the background of the increasingly mature domestic production technology of propylene glycol methyl ether acetate and the rapid development of application fields, its production capacity has continued to increase and its market size has continued to expand. According to 《 The 2022-2026 China Propylene Glycol Methyl Ether Acetate (PMA) Project Investment Feasibility Study Report shows that the domestic production capacity of propylene glycol methyl ether acetate in 2021 will be approximately 564,000 tons; the market The scale was 3.48 billion yuan, a year-on-year increase of 23.5%. From the perspective of application market, coatings, inks and electronics are currently the three major application fields of propylene glycol methyl ether acetate in China. In 2021, applications in the ink and coating fields accounted for 74% of the total domestic consumption of propylene glycol methyl ether acetate; applications in the electronic field accounted for 74% of the total domestic consumption of propylene glycol methyl ether acetate. The ratio is 20%.
At present, in the domestic electronics field, the market penetration rate of domestic propylene glycol methyl ether acetate is still relatively low, and the main products still rely on imports. The main reason for the low localization rate of propylene glycol methyl ether acetate is that the technical barriers to electronic grade propylene glycol methyl ether acetate are high, and there is a large gap between domestic production technology and foreign advanced levels. Therefore, there is still huge room for improvement of local enterprise technology in the future. .
At this stage, the main propylene glycol methyl ether acetate companies in my country include Yida Chemical, Tianyin Chemical, Hualun Chemical, Baichuan Hi-Tech New Materials, Puxin Chemical, Ruijia Chemical, etc. Among them, Tianyin Chemical is the current domestic propylene glycol methyl ether acetate production capacity. The largest company has a production capacity share of 25%; followed by Warren Chemical and Yida Chemical, with a production capacity share of 13% and 10% respectively. The three companies account for a total of 48% of the market share. At present, my country’s propylene glycol methyl ether acetate industry is highly concentrated and the industry development trend is good.
Industrial analysts personnel said that in the future, driven by the application market demand for propylene glycol methyl ether acetate, the production capacity of local enterprises will continue to expand and the industry will be concentrated. The degree is expected to continue to increase. As the market gradually moves closer to leading enterprises, local leading enterprises will continue to improve production technology and increase product research and development capabilities. In the future, domestic electronic-grade propylene glycol methyl ether acetate production capacity is expected to continue to expand, the process of domestic substitution will continue to accelerate, and the industry has broad room for development. .
