Due to limitations in downstream applications, the domestic market capacity for diglycidyl tetrahydrophthalate is not large.

Tetrahydrophthalic acid diglycidyl ester is also known as tetrahydrophthalic acid diglycidyl ester. Its molecular formula is C14H18O6 and its CAS number is 21544-03-6. It appears as a light yellow transparent viscous liquid and is a glycidyl ester ring. Oxygen resin has the characteristics of low viscosity, high reactivity, good cured mechanical properties, good electrical properties, strong adhesion, ultra-low temperature resistance, and excellent weather resistance. It can be used in composite materials, electronics industry, adhesives, coatings and other fields. .

From a production perspective, China is an important global producer of tetrahydrophthalate diglycidyl ester. Chinese companies represented by Nantong Xinaxi New Materials Co., Ltd. mainly produce tetrahydrophthalic acid and epoxy chlorine. Propane is used as raw material to produce tetrahydro-diglycidyl phthalate; companies represented by Anhui Xinyuan Technology Co., Ltd. use tetrahydrophthalic anhydride, epichlorohydrin and alkali as main raw materials to produce tetrahydro-diglycidyl phthalate. Glycidyl ester.

From the demand side, according to the“In-depth Market Research and Investment Strategy Suggestions on the Diglycidyl Tetrahydrophthalate Industry from 2023 to 2027″ released by the Industrial Research Center Report” shows that as a relatively niche epoxy resin, the market capacity of tetrahydrophthalic acid diglycidyl ester is not large. In 2022, the domestic tetrahydrophthalic acid diglycidyl ester will be The demand for glyceride is less than 300 tons, and the market size is less than 30 million yuan. From the perspective of demand structure, in 2022, the demand for tetrahydrogen diglycidyl phthalate in China’s composite materials field will account for 85.9%; the demand for tetrahydrodiglycidyl phthalate in the coating field will account for 7.3%; others Field demand accounted for 6.8%.

From the perspective of market competition, the number of manufacturing companies in the diglycidyl tetrahydrophthalate industry is relatively small. In addition, there is environmental pollution in the product production process. Affected by factors such as stricter environmental protection supervision and limited demand, domestic demand has increased in recent years. The number of diglycidyl tetrahydrophthalate companies has decreased. At present, the main companies in the diglycidyl tetrahydrophthalate industry are Anhui Xinyuan Technology Co., Ltd., Nantong Xinaxi New Materials Co., Ltd., Hubei Xinjing New Materials Co., Ltd., Guangzhou Taiji New Materials Co., Ltd., Chengdu Yuanda Chemical Co., Ltd., the market competition is relatively gentle.

Industrial analysts said that diglycidyl tetrahydrophthalate is used as a reactive diluent for epoxy resin adhesives When used, it can improve the processability, low temperature resistance, and bonding strength of epoxy resin. In the future, as the amount of tetrahydrophthalic acid diglycidyl ester mixed with other epoxy resins increases, domestic tetrahydrophthalic acid diglycidyl ester will increase. The demand for glycerides will further increase. However, due to factors such as the fact that there are not many application fields actually developed downstream and the demand for diglycidyl tetrahydrophthalate in each major application field is small, the demand for it in domestic and foreign markets is not large. This is to a large extent It has restricted the development of enterprises in the tetrahydrophthalate diglycidyl ester industry, and also led to low enthusiasm for R&D, innovation and investment in the tetrahydrophthalate diglycidyl ester industry.
