The polyphenylene sulfide (PPS) industry is accelerating the realization of localization, and companies are making plans one after another.

Polyphenylene sulfide (PPS) is one of the six special engineering plastics. It is a high-performance thermoplastic resin with good heat resistance and chemical corrosion resistance. It is widely used in electronics, automobiles, environmental protection, building materials, etc. field. In recent years, the rapid development of 5G communications and new energy fields has provided development opportunities for new materials. Compared with other engineering plastics, polyphenylene sulfide has advantages such as heat resistance and flame retardancy, and market demand continues to rise.

There are many production methods for polyphenylene sulfide, including sodium sulfide method, sulfur method, hydrogen sulfide method, and oxidative polymerization method. Among them, sodium sulfide method is currently the most important production method. Polyphenylene sulfide is mainly used in the production of engineering plastics, fibers, films and coatings, of which the plastics sector accounts for 80%. In terms of patent applications by various companies, there are more patents related to polyphenylene sulfide fiber, accounting for more than 60%.

According to the released “Report on Development Prospects and Investment Risk Avoidance Suggestions for China’s PPS Polyphenylene Sulfide Industry in 2021-2025”, my country The development of the polyphenylene sulfide industry is relatively late. Research on the synthesis and application of polyphenylene sulfide has been carried out since 1964. It has now reached the industrialization stage, and domestic production capacity continues to increase. In the past five years, my country’s polyphenylene sulfide production has continued to rise, from 15,000 tons in 2016 to 59,000 tons in 2020. In terms of the type of production enterprises, about 29,000 tons of polyphenylene sulfide in China come from foreign-funded enterprises. Polyphenylene sulfide has a wide range of applications, and has been developed in many industries such as new infrastructure, 5G communications, new energy vehicles, clean energy, etc. in recent years. The market demand for polyphenylene sulfide continues to rise, from 31,000 tons in 2016 to 6.3 Thousands of tons.

The technical threshold for the production of polyphenylene sulfide is relatively high. Currently, only a few countries in the world, such as China, the United States, Japan, and Germany, can achieve production, and there are about a dozen brands produced. In the world, the polyphenylene sulfide markets in Japan and North America are relatively mature and have little room for future growth. As the Asia-Pacific region except Japan is in a stage of rapid economic development, the demand for polyphenylene sulfide is high, and the market development potential is huge in the future.

my country’s polyphenylene sulfide market demand continues to rise, but production growth is slow and it is difficult to meet domestic market demand, so a large amount of imports are still needed. In order to achieve domestic substitution, domestic companies have deployed and built new production equipment. Currently, the leading polyphenylene sulfide manufacturers in China include Xiyu Special New Materials, Xinhecheng Co., Ltd., Yiteng Hi-Tech, Xinsheng New Materials, Deyang Chemical, Haohua Honghe Chemical, Ruitai Technology, etc.

Industrial analysts said that polyphenylene sulfide has superior performance and a wide range of applications, benefiting from the development of terminal industries, polyphenylene sulfide Market demand is rising and the industry is developing rapidly. In recent years, my country’s polyphenylene sulfide production and demand have increased, but the growth rate of production cannot meet market demand, so it still relies on imports. In terms of market competition, there are many companies in our country, the market is relatively fragmented, and no leading company has yet emerged.
