Polynaphthalene biphenyl polyethersulfone ketone (PPESK) has excellent comprehensive properties and China’s production capacity will gradually expand
Polynaphthalene biphenyl polyethersulfone ketone (PPESK) has excellent comprehensive properties and is resistant to strong acid and alkali corrosion, organic solvent resistance, high temperature resistance, and excellent insulation. It is a new type of special engineering plastic that can be widely used in coatings, Resin paint, enameled wire, membrane material manufacturing and other fields.
The preparation process of naphthylbiphenyl polyethersulfone ketone mainly uses diazinone bisphenol monomer (DHPZ), 4,4′-dichlorodiphenylsulfone, and difluorobenzophenone as raw materials, and dimethyl Acetamide is used as the solvent, anhydrous potassium carbonate is added as the catalyst, toluene is used as the water-carrying agent, and it is copolymerized under certain temperature conditions.
Polyaryl ether sulfone (PES) and polyaryl ether ketone (PEK) are engineering plastics with excellent comprehensive properties. Based on them, polyaryl ether sulfone (PPES) and polyaryl ether ketone (PPEK) are manufactured. , the product’s solubility, glass transition temperature and other properties are improved. According to the “2022-2027 China’s Polynaphthalene Polyethersulfone Ketone (PPESK) Industry Market In-depth Research and Development Prospects Forecast Report” released by the Industrial Research Center strong> It shows that polyethersulfone ketone has excellent heat resistance, but has poor fluidity and difficult processing. Referring to PPES and PPEK, heteronaphthalene biphenyl polyethersulfone ketone was copolymerized. Its previous properties such as high temperature resistance are retained, and it has the advantages of both PPES and PPEK, and its processing performance is better, so it has attracted attention. .
Due to the strong corrosion resistance of heteronaphthalene biphenyl polyethersulfone ketone, it has broad prospects in the field of manufacturing various membrane materials, such as ultrafiltration membranes. In order to further improve the comprehensive performance and expand the scope of application, research on the modification of heteronaphthalene biphenyl polyethersulfone ketones continues to be in-depth. The ultrafine fiber membrane is produced by blending heteronaphthalene biphenyl polyethersulfone ketone and polystyrene using electrospinning technology, and the product strength is significantly improved. Other materials that have been studied and can be used in the field of polyethersulfone ketone modification include polyethylene terephthalate, silane coupling agents, liquid crystal polymers, multi-walled carbon nanotubes, carbon fibers, and glass. fiber etc. In addition, heteronaphthalene biphenyl polyethersulfone ketone can also be used to modify other polymer materials, such as epoxy resin, which greatly increases the glass transition temperature of the product.
Industry analysts said that due to its excellent comprehensive performance, the Chinese government is paying high attention to the development of the heteronaphthalene biphenyl polyethersulfone ketone industry. In the “Made in China 2025” strategy, the special engineering plastics sector under the new material category proposes to focus on the development of special fibers, filter materials, and high-temperature resistant materials processed and molded based on polynaphthalene biphenyl polyethersulfone ketone copolymer resin (PPESK). Functional films, high-performance resin-based composite materials, etc. This will help promote the continuous expansion of my country’s production scale of heteronaphthalene biphenyl polyethersulfone ketone.
Chengdu Tianshun Poly New Materials Co., Ltd. plans to build a 2,500-ton new heterocyclic high-performance plastics project in the Chengdu New Materials Industry Functional Zone. The first phase plans to build 500 tons of new heterocyclic high-performance plastics, and the second phase plans to build a 2,000-ton new heterocyclic high-performance plastics project. Performance Plastics, which includes polynaphthalene biphenyl polyethersulfone ketone (PPESK) capabilities. From this point of view, my country’s heteronaphthalene biphenyl polyethersulfone ketone production capacity is expected to gradually expand.
