This article is from the WeChat official account “Youhua Xiaocai”. I. Industry background of the project: 1. Global PPS market size: In 2017, the global PPS market size was 10.4 billion US dollars, representing a year-on-year increase of 16.5%; it is expected that by 2022, this market size will reach 17.76 billion US dollars； 2. Current status of PPS production abroad: The main regions where PPS is produced are Japan, the United States, and China. Japanese companies account for around 40% of the global production capacity, with Toray and DIC being the key players in this field. As of the end of 2017, the global production capacity of PPS was estimated to be around 157,000 tons. 3. Projections for domestic PPS production and demand ； In 2017, China’s PPS production reached 29,100 tons, a year-on-year increase of 20.24% ； The demand volume was 137,400 tons, representing a year-on-year increase of 14.98%. At present, China’s PPS industry is in a period of rapid development; it is estimated that by 2022, production will reach 72,400 tons, while demand will reach 277,500 tons ； 4. Current status of PPS applications: Global usage in 2018 (kt): 79.2% in the automotive industry ； Electronics and Electrical 29.4% ； Fiber 10.6% and others 0.2% ； 5. PPS development trends: ① Development of composite materials with low warpage and high toughness ； ②Improve the shortcomings of PPS by endowing it with high functionality, ultra-precise formability, and improved lubricity ； ③Changing the structural characteristics of PPS, such as its degree of branching, endows it with special properties ； ④Expand the application fields of PPS and its composites, such as in new energy vehicles, electronics, and electrical appliances. II. Technical Advantages
1. It utilizes a foreign-developed lithium-free catalytic sodium sulfide process, which is a mature technology. The market positioning is on high-end products within the modified plastics sector (modified plastics account for approximately 80% of the total PPS market) ； 2. Compared with domestic production processes ； ①Low cost: Using water as a catalyst reduces the raw material cost by nearly 4/5 compared to using LiCl as a catalyst in China ； ②Good product performance: Uniform particle size distribution of PPS ； Resins for molding/fiber use can be produced ； Low content of oligomers in the product. ③ NMP solvent recovery: Recovery is possible without the need for a catalyst, eliminating the need for a catalyst recovery unit ； Economical and efficient. In summary, when comparing the properties of the PPS resin produced by this process with those of domestic products: for PPS with a similar fiber content, its tensile strength, flexural strength/modulus, and insulation breakdown strength are all superior to those of products available on the domestic market. III. Introduction to the Expert Team 1. The expert technical team comes from internationally renowned companies and possesses extensive experience in the development, modification, and consultation of PPS resins. Comprehensive technical control capabilities across the entire industry chain, from resin polymerization and modification to the development of downstream products ； 2. A PPS development and line-construction project is staffed with 3 principal overseas technical experts, as well as project managers to ensure the smooth implementation of the project ； 3. Key advisor: Male DB, bachelor’s degree in production machinery engineering, Japanese nationality, 63 years old ； Work experience: ① Over 20 years of experience at a globally renowned engineering plastics company; ② Responsible for the relocation of production to Japan and for the establishment of 5 manufacturing plants in the Asia-Pacific region (in Japan, South Korea, China, Singapore, and Thailand), all of which produce engineering plastics such as PC, PBT, PPE, PPS, and PEI – each with a production capacity of around 50,000 tons per year – as well as acting as the on-site manager to ensure stable supply to customers; ③ Has served as the company’s head of manufacturing and head of production technology.
