Headquartered in Hangzhou, China, Rongsheng Petrochemical Co., Ltd. is a key subsidiary of the Zhejiang Rongsheng Holding Group—a Fortune Global 500 company—and stands as one of China’s leading private petrochemical enterprises.
The company specializes in the R&D, production, and sales of petrochemical products. Over the years, it has developed a comprehensive, integrated industrial chain spanning from oil refining and aromatics/olefins to purified terephthalic acid (PTA), ethylene glycol, and polyester (including fibers, PET chips, and films). Rongsheng Petrochemical demonstrates exceptional competitiveness in the production capacity of core chemicals such as PTA and paraxylene (PX), while also maintaining robust production capabilities for polyethylene, polypropylene, EVA, and ABS. Currently, the company ranks 11th on the ICIS "Top 100 Chemical Companies" list, 6th on *Chemical Week*'s "Billion Dollar Club" global ranking, and 6th on the list of the "Top 25 Most Valuable Chemical Brands" published by the renowned British brand valuation and strategy consultancy, Brand Finance.
Through its subsidiary, Zhejiang Petroleum & Chemical Co., Ltd., the company operates a 40-million-ton-per-year integrated refining and chemical complex, serving as a major producer of polyester, new energy materials, engineering plastics, and high-value-added polyolefins in China and across Asia. Another subsidiary, Ningbo Zhongjin Petrochemical Co., Ltd., operates a 2-million-ton-per-year aromatics unit—one of the largest single-train capacities of its kind in China. Furthermore, by establishing PTA production facilities in Ningbo, Dalian, and Hainan with a combined capacity exceeding 20 million tons, Rongsheng Petrochemical has become a global heavyweight in PTA production. The company is also actively expanding into the sector of high-end petrochemical-based new materials.
In the downstream polyester sector, Rongsheng Petrochemical has established a presence in polyester fibers, PET chips, and polyester films. The company is proactively building intelligent, digitalized production facilities; it was among the first in China to introduce advanced industrial automation assembly lines across the entire polyester fiber production process, effectively implementing "machine-for-human" labor substitution. The company is committed to quality-driven development. Its core products have obtained ISO9001, ISO14001, OHSAS18001, and Oeko-Tex Standard 100 certifications, as well as the "Made in Zhejiang" (Zhejiang Manufacturing) certification. Rongsheng Petrochemical actively establishes diverse R&D platforms, employing a dual-driven approach—combining "independent innovation" with "open cooperation"—to continuously elevate its scientific research capabilities.
To date, the company has built a substantial portfolio of proprietary intellectual property, which has effectively propelled its innovation-led growth. Guided by the corporate mission to "serve the nation through industrial development and lead the progress of the sector," Rongsheng Petrochemical pursues industrial value while remaining deeply committed to its social responsibilities. The company enforces rigorous, integrated oversight of safety and environmental protection, promotes advanced low-energy technologies and equipment, and manufactures eco-friendly products. Through these concrete actions, it injects "green energy" into the industry, helping to safeguard our natural environment—our "clear waters and lush mountains."
