BPEF (bis-ether fluorene) has broad application prospects in the field of machine vision. Zhongxin Fluorine Materials is a leading company in my country

BPEF is bisether fluorene, the full name is 9,9-bis[(4-hydroxyethoxy)phenyl]fluorene. It is a type of bisphenol fluorene compound with the chemical formula C29H26O4. It appears as a white powder and is soluble in toluene. , absolute ethanol, acetone, ethyl acetate and methylene chloride and other organic solvents. The main production method of BPEF is to use 9-fluorenone and phenoxyethanol as raw materials, and generate BPEF through condensation reaction, extraction, neutralization, washing, recrystallization and other steps.

BPEF is a polymer material monomer with high stability. It is widely used in the synthesis of polymer materials such as polyester, polyether, polyether, epoxy resin, polycarbonate, and polyacrylate. The terminal fields include automobiles, Electronics, optical devices, smart home, aerospace, national defense and military industry, etc.

Specifically, polycarbonate synthesized with BPEF as a monomer has good wear resistance, heat resistance and high refractive index, and can be used in high-end optical resin lens manufacturing scenarios such as camera lenses, drone lenses, and vehicle camera lenses; Epoxy resin synthesized with BPEF as a monomer has high viscosity and high heat resistance, and can be used in chip packaging, display manufacturing and other scenarios.

Among them, high-end optical resin lenses are the main downstream products of BPEF. The optical lens is an indispensable component in the machine vision system and has a direct impact on the machine imaging effect. High-end optical resin lenses are upgraded products of optical lenses and are suitable for high-end equipment such as drones and automobiles. Currently, against the background of the continuous development of high-tech fields such as domestic automobiles and aviation, the demand for high-end optical resin lenses continues to increase, which in turn drives the continued growth of BPEF demand.

According to the “2023-2028 BPEF (bis ether fluorene) industry market in-depth research and investment prospect forecast analysis report” released by the Industrial Research Center It is shown that the size of my country’s machine vision market has exceeded 20 billion yuan in 2022, and is expected to be close to 50 billion yuan by 2028. Against this background, the domestic BPEF market demand has exceeded 5,000 tons in 2022, and the market demand space is vast.

At present, the number of companies with BPEF mass production capabilities in my country is relatively small, mainly including Zhejiang Zhongxin Fluoro Materials Co., Ltd., Sinochem Hebei, Sinosteel Tianyuan, Jiangsu Yongxing Chemical Co., Ltd., Shanxi Jinjing Chemical Co., Ltd., Huanghua Xinnuo Lixing, Hebei Sinochem Xinbao Chemical Technology and others are mostly small and medium-sized enterprises. Among them, Zhongxin Fluorine Materials is a leading company in the domestic BPEF industry. At present, the company’s annual BPEF production capacity has reached 1,500 tons. At the same time, the company is actively expanding its BPEF production. In the future, with the company’s “annual output of 1,420 tons of fluorine fine chemicals and 5,200 tons of photoelectric material series “Product Construction Project” has been accelerated, and BPEF’s annual production capacity is expected to increase to 3,500 tons.

Industry analysts said that BPEF is a synthetic polyester, polyether, polyether, epoxy resin, An important monomer for polymer materials such as polycarbonate and polyacrylate, the demand for BPEF continues to increase amid the rapid development of the polymer materials application market, and the industry shows good development prospects. From the production side, the number of BPEF manufacturers in my country is relatively small, and most of them are small and medium-sized enterprises with low production capacity and difficulty in meeting market demand. Therefore, in the future, local companies will need to continue to improve their technical level and increase production capacity expansion.
