The market size of trimethyl borate (TMB) continues to expand, with the electronic and electrical field as its emerging demand end.

​​​​ Trimethylborate (TMB), also known as trimethoxyborane, has a chemical formula of C3H9BO3 and is an organic compound. Trimethyl borate appears as a colorless and transparent liquid and is soluble in organic solvents such as methanol, tetrahydrofuran and ether. Trimethyl borate has the characteristics of being easily hydrolyzed and flammable, and is widely used in petrochemical, electronic and electrical, spices, ceramic materials, medicine and other fields.

The preparation methods of trimethyl borate include boron halide extraction, boric acid extraction, boron fluoride extraction, and pyridine-boron trifluoride complex extraction. The boric acid extraction method is the mainstream preparation method for trimethyl borate. It uses solid boric acid as raw material, produces pyboric acid and metaboric acid through processes such as heating and drying, and then adds methanol to obtain trimethyl borate through a full reaction. In recent years, with technological advancement and sufficient supply of raw materials, the output and quality of trimethyl borate in my country have been further improved.

         Trimethyl borate is widely used, including petrochemicals, electronics and electrical, spices, ceramic materials, medicine, etc. The petrochemical industry is the traditional application field of trimethyl borate. It can be used as catalyst, vulcanizing agent, heat stabilizer, gelling agent, resin solvent, etc. As downstream demand becomes increasingly strong, the market size of trimethyl borate continues to expand. According to the “2023-2028 China Trimethyl Borate (TMB) Industry Market In-depth Research and Development Prospects Forecast Report》shows that the global trimethyl borate market will reach US$250 million in 2022, a year-on-year growth of 5.2%.

The electronic and electrical field is an emerging application field for trimethyl borate. In recent years, thanks to the accelerating update and iteration of electronic products, the prosperity of my country’s lithium battery industry has continued to increase. Trimethyl borate can be used as a polar film-forming additive for LiCoO2 batteries, which can effectively improve the high voltage performance and cycle performance of the battery. Attracted by the market prospects, Chinese enterprises and scientific research institutions continue to increase research on the application of trimethyl borate in the field of trimethyl borate, and have made many new developments, driving the industry’s development trend to continue to improve.

The main manufacturers of trimethyl borate in my country include Suzhou Senfida Chemical Co., Ltd., Jiangsu Hongzi New Energy Technology Co., Ltd., Anhui Wotu Chemical Co., Ltd., Guobang Pharmaceutical Group Co., Ltd., Wuhan Chujiang Haoyu Chemical Technology Development Co., Ltd., etc. At present, Chinese enterprises mainly produce industrial grade and pharmaceutical grade trimethyl borate, and electronic grade trimethyl borate is highly dependent on imports.

Industry analysts said that trimethyl borate has excellent performance and has broad application prospects in the electronic and electrical fields. With the boom of the lithium battery industry With continuous improvement, my country’s market demand for trimethyl borate will further grow. There are many trimethyl borate manufacturers in my country, and industrial grade trimethyl borate and pharmaceutical grade trimethyl borate occupy a large share of the market. In the future, with technological advancement, the localization process of electronic grade trimethyl borate in my country is expected to accelerate.
