On November 19, 2025, Sinopec Yanshan Petrochemical Company and Tianjin Economic Development Zone Management Committee officially signed a "Letter of Intent for Investment Cooperation", marking the full implementation stage of the Tianjin Nangang Green High end Rubber New Material Project with a total investment of about 6 billion yuan. This is another important strategic layout of Sinopec Yanshan (Tianjin) Petrochemical Co., Ltd. in Tianjin Nangang Industrial Zone since its establishment in June 2025, which will effectively promote the innovative development of China's high-end new materials industry.

The project will be promoted in two phases to create a green high-end industrial chain

The project is located in Nangang Industrial Zone, Tianjin, covering an area of 27.7 hectares. It is a key project of Sinopec Yanshan Petrochemical's overall plan for "deepening local cultivation and building factories in other places". The overall plan of the project will be promoted in two phases: the first phase will invest 2.42 billion yuan to build two sets of production facilities, 100000 tons/year solution polymerized styrene butadiene rubber and 100000 tons/year butadiene rubber, and provide corresponding auxiliary facilities; The second phase plans to plan the Yanshan Petrochemical characteristic advantage project, which will be launched in a timely manner based on the construction, process, and market conditions of the first phase project. Since the feasibility study report of the project was approved by Sinopec Group on February 12, 2025, it has gone through key milestones such as enterprise registration and basic design approval. On October 25, the pile driving construction officially began, marking an important milestone.

Guided by technological innovation, our products accurately meet the demands of the high-end market

In the context of dual carbon, the project has been aimed at national and Tianjin industrial policy guidance from the beginning of planning, anchoring its "green high-end" positioning. Solution polymerized styrene butadiene rubber has excellent properties such as high strength, good wear resistance, and low rolling resistance, making it an ideal material for high-performance tire manufacturing; Shunding rubber is known for its excellent cold resistance, wear resistance, and elasticity. The mixed use of two products can significantly improve the comprehensive performance of materials, perfectly meeting the needs of new energy vehicles for low-noise and low rolling resistance tires. The project will fully utilize the C4 resources of Tianjin Nangang Ethylene and Zhongsha Ethylene, adopt new process packages, and rely on the mature supporting facilities of Nangang Industrial Zone to build a complete green high-end industrial chain from raw materials to end products.

The industrial cluster effect of Nangang is prominent, and the formation of a billion dollar industrial chain is accelerating

After 16 years of development, Tianjin Nangang Industrial Zone has formed a sizable petrochemical industry cluster. In addition to the rubber project that started this time, Sinopec's 1.2 million tons/year ethylene project, as a key project of the 14th Five Year Plan, has a total investment of over 30 billion yuan and was successfully launched in November 2024; Creating a benchmark for smart factories in catalyst production bases; Hydrogen energy industry construction comprehensive energy demonstration station. At the same time, enterprises such as Bohua Nangang New Materials Industrial Park and Tianjin Xinhecheng Material Technology Co., Ltd. have invested over 40 billion yuan to jointly build a complete petrochemical new materials industry chain. These projects will drive the formation of downstream industries worth billions of yuan, significantly enhancing China's independent guarantee capability in the field of high-end new materials, and injecting strong impetus into the high-quality development of the manufacturing industry.
