Heteronaphthalene biphenyl polyethersulfone is a new type of special engineering plastics with high wear resistance, excellent heat resistance and mechanical properties and good electrical insulation properties. This material is produced by copolymerisation of diazanaphthone bisphenol monomer (DHPZ), 4,4′-dichlorodiphenylsulfone, and difluorodiphenyl ketone as raw materials through a specific preparation process. The glass transition temperature of heteronaphthalene biphenyl polyethersulfone is between 263℃～305℃, and its comprehensive performance is excellent, which can be used in aerospace, high-speed rail, nuclear energy, precision machinery, automotive, petrochemical, nuclear energy and other fields.
Heteronaphthalene biphenyl polyethersulfone has the advantages of high abrasion resistance, excellent heat resistance and mechanical properties as well as good electrical insulation, etc. It is a new type of high-performance special engineering plastics with great R & D potential and has good application prospects. On the one hand, the support of national policy for the development of heteronaphthalene biphenyl polyethersulfone provides a good industrial policy environment. Made in China 2025″ puts forward the focus on the development of thermoplastic polyimide (PI) engineering plastic resins, heteronaphthalene biphenyl polyethersulfone and other engineering plastics production and co-mingling modification, alloying technology development and application; “Industrial Structure Adjustment Guidance Catalogue (2019 Edition)” will be “polyphenylene ether, aryl ketone polymers, polyaryl ether nitrile and other engineering plastics production and co-mingling modification, Alloying technology development and application, high water-absorbent resins, conductive resins and biodegradable polymers development and production” as an encouraged industry; “14th Five-Year Plan” Chemical New Materials Industry Development Guide pointed out that we should vigorously develop polysulfone, polyphenylsulfone, polyetheretherketone, liquid crystal polymers and other high-performance engineering plastics. In addition, the state also promulgated the “Guidelines on the Development of New Chemical Materials Industry in the 14th Five-Year Plan”. In addition, the state also promulgated the “fourteenth five-year plan” to promote high-quality development of the petrochemical and chemical industry, “fourteenth five-year plan” raw materials industry development plan “and other policies also promote the development of heteronaphthalene biphenyl polyethersulfone industry.
On the other hand, heteronaphthalene biphenyl polyethersulfone is a new type of thermoplastic resin material with excellent comprehensive performance, and its downstream applications cover aerospace, precision machinery, automotive manufacturing, and engineering and other high-tech fields and civil fields. Due to its excellent heat resistance, wear resistance, mechanical properties and electrical insulation, heteronaphthalene biphenyl polyethersulfone has become an ideal material choice in these fields. In the future, with the continuous enhancement of the supply capacity of heteronaphthalene biphenyl polyethersulfone and the continuous development of the downstream industry, coupled with the enhancement of the penetration rate of heteronaphthalene biphenyl polyethersulfone and the expansion of the scope of application of the product, the market demand for heteronaphthalene biphenyl polyethersulfone will grow rapidly.
Production, heteronaphthalene biphenyl polyethersulfone is a special engineering plastics researched and developed by the research team of Professor Jian Xigao of Dalian University of Technology at the end of the 1990s, and its industrialisation time is relatively short, and there are limitations in terms of patents, technology, etc., which results in fewer enterprises with the production capacity of heteronaphthalene biphenyl polyethersulfone. At present, only Chengdu Tianshun Poly New Material Co., Ltd. has built a 500 tonnes/year heteronaphthalene biphenyl polyethersulfone production unit, which was put into production in March 2023. According to the “2022-2027 China Heteronaphthalene Biphenyl Polyethersulfone Ketone (PPESK) Industry Market Depth Research and Development Prospect Forecast Report” released by Xinsiye Industry Research Centre, China’s heteronaphthalene biphenyl polyethersulfone ketone production in 2023 was 55 tons.
Industry analysts believe that the comprehensive performance of heteronaphthalene biphenyl polyethersulfone ketone is excellent, especially the heat resistance is significantly better than other polymers of the same type, is a key concern of China’s new materials products, composite materials, high temperature functional film, high temperature functional coatings, and other areas with good application prospects. In the future, heteronaphthalene biphenyl polyethersulfone market demand or will grow rapidly, but at present the domestic heteronaphthalene biphenyl polyethersulfone production capacity is still weak, so the industry has a larger development space, investors can focus on the field.
