The application scope of benzoxazine (BOZ) continues to expand, and my country’s industry concentration is high

Benzoxazine (BOZ) refers to the general name of compounds containing N and O six-membered oxazine rings in their structure. It is a new type of thermosetting resin. Compared with other thermosetting resins, benzoxazine has the advantages of good heat resistance, high modulus, low water absorption, and high strength. It is widely used in composite materials, refractory materials, insulation materials, medicine, electronic components and other fields. According to different structures, benzoxazines can be divided into DCPD-type benzoxazines, bisphenol-A-type benzoxazines, MDA-type benzoxazines, and bisphenol-F-type benzoxazines.

Benzoxazines are usually produced from formaldehyde, primary amines and phenol. As the concept of green environmental protection continues to deepen, biomass materials such as cashew phenol, biomass methanol, lignin-decomposed phenol, and phenolphthalein furfurylamine are gradually used in the production process of benzoxazine. It is expected that the market share of bio-based benzoxazines will continue to increase in the future.

According to the “2023-2028 China Benzoxazine (BOZ) Industry Market In-depth Research and Development Prospects Forecast Report》shows that as a new type of thermosetting resin, benzoxazine is widely used in composite materials, refractory materials, insulation materials, medicine, electronic components and other fields. In the field of composite materials, benzoxazine has excellent heat resistance and can be used to produce composite materials for aviation and automobiles; in the field of medicine, benzoxazine can be used to produce anti-breast cancer drugs, drugs to stabilize arteriosclerotic plaques, etc.; In the field of electronic components, benzoxazine can be used as a high-performance chip packaging material.

In recent years, as research continues to deepen, the application scope of benzoxazines continues to expand. In March 2023, Liu Jian’s team at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Wu Limin’s team at Fudan University/Inner Mongolia University jointly developed a photocatalyst with excellent stability and extremely high hydrogen peroxide yield. The product is based on benzo Oxazine-based phenolic resin is made from raw materials and is expected to be widely used in the fields of new energy and environmental protection in the future.

There are few benzoxazine manufacturers in my country and the industry concentration is high. The main market participants include Puyang Enying Polymer Materials Co., Ltd., Tongyu New Materials (Guangdong) Co., Ltd., Chengdu Keyi Polymer Technology Co., Ltd., Sichuan Dongcai Technology Group Co., Ltd., Jinan Shengquan Group Co., Ltd., etc. Keyi Polymer is my country’s leading benzoxazine enterprise. The company focuses on the research, development, production and sales of insulating materials, electronic materials, benzoxazines, abrasive materials, and anti-corrosion coatings. The benzoxazines it produces are flame retardant. Excellent.

Industry analysts said that benzoxazine, as a new thermosetting resin, has excellent performance and a wide range of uses. As research continues to deepen, the application scope of benzoxazine is expected to be further expanded. my country’s benzoxazine industry started late, but is developing rapidly. Keyi Polymer, as the leading benzoxazine company in my country, continues to increase investment in the research and development of high-performance products, and its market share will further increase in the future.
