my country’s polyphenylsulfone (PPSU) import dependence is high and there is huge room for domestic substitution.

Polyphenylsulfone (PPSU), also known as polyphenylene sulfone resin, is an amorphous thermoplastic engineering plastic formed by the condensation polymerization of bis-aromatic sulfonyl chloride and aromatic rings. Because the molecular chain contains a large number of biphenyl groups, polyphenylsulfone has more outstanding heat resistance. At the same time, polyphenylsulfone also has good transparency and hydrolytic stability. It is one of the special engineering plastics with excellent comprehensive properties and is widely used. In the fields of medical equipment, aviation industry, automobiles, petroleum machinery, high temperature equipment, plastic milk bottles, electronic cigarettes and other fields.

In the field of electronic cigarettes, polyphenylsulfone is mainly used in the upper shell of high-end electronic cigarettes. It is currently used in IQOS, CIGRIG, QOQ and other electronic cigarettes. Baby bottles are one of the typical applications of polyphenylsulfone, so polyphenylsulfone is also called “baby bottle material”. my country has a huge population base. With the gradual implementation of the tripeptide policy, the market demand for baby bottles will continue to be released, which will in turn drive the growth of polyphenylsulfone. Market demand is growing, and polyphenylsulfone is expected to become one of the strongest growing varieties in the sulfone polymer market in the future.

According to the “2021-2025 Global Polyphenylsulfone (PPSU) Industry In-depth Market Research and Key Area Research Report released by the Industrial Research Center 》 shows that with the upgrading of market demand and the acceleration of urbanization and industrialization, the global market demand for polyphenylsulfone has continued to grow. By 2020, the global market demand for polyphenylsulfone has reached more than 60,000 tons.

As a high-performance engineering plastic product, polyphenylsulfone has a complex production process and high industry entry barriers. Therefore, the number of global production companies is small. Related companies are mainly concentrated in the United States, Western Europe, and Japan. Representative companies include BASF of Germany and Solvay. wait. The number of polyphenylsulfone manufacturers in my country is also relatively small, mainly including a few companies such as Guangdong Youju New Materials, Haoran Special Plastics, Shandong Jinlan Special Polymers, and Jida Special Plastics.

4,4′-Dihydroxybiphenyl is one of the raw materials for the production of polyphenylsulfone. Our country has its mass production capacity, but there is a big gap with foreign levels in terms of quality, scale, etc. Due to limitations in raw materials and technology, currently my country’s polyphenylene sulfone production Sulfone production capacity is limited, and domestic production capacity is far from meeting the growing domestic market demand. Therefore, my country’s polyphenylsulfone import dependence is high. However, with the increase in the number of deployed enterprises and the advancement of related technologies, my country’s polyphenylsulfone production capacity is constantly improving, and the pace of domestic substitution of products is accelerating.

Industry analysts said that as a high-performance special plastic, the polyphenylsulfone industry has high technical barriers and is limited by technology, raw materials, etc. Polyphenylsulfone production capacity is limited, and the current market still relies on imports. In recent years, with the active deployment of domestic enterprises, my country’s polyphenylsulfone production capacity has improved to a certain extent. As related projects under construction and proposed are put into production, the localization rate of polyphenylsulfone will continue to increase, and the industry will have broad room for development in the future.
