Sinopec Shanghai Petrochemical Co., Ltd. (600688.SH / 00338.HK) is China’s first integrated refining and chemical enterprise listed simultaneously both domestically and overseas, established with approval from the State Economic and Trade Commission. It is positioned as a modern energy and chemical enterprise integrating oil refining, petrochemicals, and combined heat and power generation. The Company’s core businesses encompass petroleum refining (e.g., gasoline, diesel, jet fuel), ethylene and downstream chemical products (e.g., polyethylene, polypropylene, ethylene glycol, para-xylene, carbon fiber precursor), synthetic resins, synthetic rubber, organic chemical feedstocks, and green energy services. It continuously advances the transformation of “oil-to-chemicals” and “oil-to-specialty-products,” focusing on high-value-added new materials such as high-performance polyolefins, specialty epoxy resins, lithium-ion battery separator-grade materials, and carbon fiber composite materials. The Company possesses an integrated crude oil processing capacity of 24 million tons per year and an ethylene production capacity of 1.1 million tons per year. It has constructed China’s first single-line 48K large-tow carbon fiber production line, establishing a complete industrial chain—from precursor fiber, oxidation, carbonization to composite material applications—whose related technologies have been awarded the Second Prize of the National Science and Technology Progress Award, and it holds over 50 carbon fiber-related invention patents. In terms of qualifications, the Company has obtained certifications for the ISO 9001, ISO 14001, and ISO 45001 management systems; holds licenses for hazardous chemical production safety, pollutant discharge, and electricity business (power supply category); and is recognized as a National High-Tech Enterprise, a demonstration “Green Factory,” and the host unit of Sinopec’s Key Laboratory for Carbon Fiber and Its Composite Materials. Representative projects include leading the formulation of the industry standard “PAN-Based Large-Tow Carbon Fiber” (FZ/T 54143–2022); constructing China’s first pilot demonstration project integrating “green electricity + energy storage + water electrolysis hydrogen production” at a refining and chemical enterprise (commissioned in 2024); and participating in the development of the Yangtze River Delta Hydrogen Corridor. Refined petroleum product supply covers the six provinces and one municipality of East China. Internationally, its business primarily involves carbon fiber engineering design and technical service exports targeting Southeast Asia and Central Asia, enabling collaborative R&D of new materials, technology licensing, engineering consultancy, customized product supply, and cooperation on green energy projects.
