The market size of cyanate ester resin (CE) continues to expand, and my country’s production capacity is gradually improving

Cyanate ester resin, also known as triazine A resin, referred to as CE, with the molecular formula NCO-R-OCN, is a new thermosetting resin containing two or more cyanate ester functional groups (-OCN) in its molecular structure. Cyanate ester resin is solid or semi-solid at room temperature. It is soluble in common solvents such as acetone, methyl ethyl ketone, chloroform, and tetrahydrofuran. It can be softened in the temperature range of 50-60°C. It is an important type of high-temperature resistant resin. There are various types of cyanate ester resin. Common varieties include bisphenol A cyanate ester resin, bisphenol E cyanate ester resin, tetramethyl bisphenol F cyanate ester resin, etc.

Cyanate ester resin has excellent properties. It has good high-temperature mechanical properties, moisture and heat resistance, dielectric properties, flame retardant properties, dimensional stability, chemical resistance, and low water absorption. It can be used as new electronic materials, insulation materials, and 3D printing materials. It is used in national defense, aerospace, semiconductor, integrated circuit, electronic packaging, radome and other fields. At the same time, cyanate ester resin has good compatibility and high wave transmittance, and can also be used in other resin modification fields and wave-transparent material manufacturing fields.

According to the “China Cyanate Resin (CE) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center shows that cyanate ester resin has a wide range of applications and has become one of the most promising new thermosetting resin materials. In recent years, against the background of the gradual development and expansion of domestic cyanate ester resin application fields, its market demand has continued to increase and its scale has continued to expand. The domestic cyanate ester resin market size will reach 860 million yuan in 2022, a year-on-year increase of 12.4%.

At present, the main production method of cyanate ester resin refers to using cyanogen halides (cyanogen chloride, cyanogen bromide, cyanogen iodide, etc.) and phenolic compounds (bisphenol A) as raw materials, and generating cyanic acid through a chemical reaction in the presence of alkali. Ester resin process. Among them, cyanogen chloride is a highly toxic chemical. Due to limitations in raw materials and technology, the domestic cyanate ester resin market has long been dominated by international companies, including Huntsman of the United States and Lonza Group of Switzerland.

However, in recent years, through continuous research and development, some companies in my country have the capacity to produce cyanate resin in batches, such as Yangzhou Tianqi New Materials and Inner Mongolia Huansheng Technology. Among them, Tianqi New Materials is the main supplier of cyanate ester resin in my country. Currently, the company has a cyanate ester resin production line with an annual output of 300 tons, and is accelerating the construction of an 800 tons/year cyanate ester resin project. In the future, under the background of the gradual release of cyanate ester resin production capacity of domestic enterprises, the level of localization in our country’s market will continue to improve.

Industrial analysts said that cyanate ester resin is a new type of thermosetting resin material with excellent performance. The defense industry, aerospace, semiconductor and other fields show great development prospects. After continuous research and development, my country’s cyanate ester resin production capacity is gradually improving. However, compared with developed countries, the development of the domestic industry is still relatively backward. In the future, local enterprises will need to continue to increase technology research and development efforts and improve technology levels, and then continue to shrink. gap with developed countries.
