China Lianyungang Petrochemical 7.79 billion Yuan High-end New Materials Project Announced Before Approval, Production in 2027

Recently, China Lianyungang Xuwei New District Environmental Protection Bureau officially released Lianyungang Petrochemical Co., Ltd. high-end new materials project environmental impact assessment documents to be approved for publicity. This major project with a total investment of 7.792 billion billion yuan and environmental protection investment of 0.953 billion billion yuan (accounting for 12.2) marks another large-scale production capacity in China's polyolefin and high-end elastomer field has entered the sprint construction stage. For participants in the global chemical trade chain, this is a supply pattern variable worth studying in advance.

1. five major devices landed in stages, the main production capacity priority into the market.

Five core units are planned for the project. The construction site is located in Lianyungang Petrochemical Industry Base, Jiangsu Province, China. It is planned to be fully put into operation in August 2027: polyethylene 900000 tons/year, butadiene extraction 120000 tons/year, α-olefin (LAO) 100000 tons/year, polyolefin elastomer (POE) 100000 tons/year, 1-butene 50000 tons/year.

The construction adopts a two-stage promotion strategy: the first stage gives priority to the construction of polyethylene and 1-butene devices, taking the lead in locking the market window of the main volume of products, and the second stage to promote butadiene extraction, LAO and POE three sets of devices, and gradually release high value-added capacity. This rhythm arrangement not only takes into account the pressure of capital and technology, but also strives for the space for enterprises to recover cash flow as soon as possible.

Environmental protection investment accounts for 12.2 per cent of the industry's high level, which is highly compatible with the increasingly stringent environmental compliance requirements of China's chemical parks and reflects the project's forward-looking layout in green compliance-an important compliance reference dimension for overseas purchasers interested in long-term cooperation with Chinese suppliers.

2. technology breakthrough and market impact: from "stuck neck" to large-scale output

the most strategic highlight of this project is the independent research and development of the parent company Satellite Chemical. Ethylene oligomerization to 1-butene technology to achieve localization landing. The technology has been monopolized by overseas enterprises for a long time, which is a typical link in China's polyethylene industry chain. After the breakthrough of localization, the supply of 1-butene, a key comonomer, will no longer rely on foreign authorization, and the degree of independent control of China's polyethylene industry chain will be substantially improved.

From the downstream application point of view, the project will cover high-end polyolefin and POE products, widely used in photovoltaic film, auto parts and high-end packaging and other end markets. These segments are currently highly dependent on imported materials. With the release of China's large-scale production capacity in 2027, the global procurement pattern and price system of related categories will face restructuring-for overseas suppliers who rely on exporting POE or high-end polyethylene to China, the pressure of market space compression is worth assessing in advance.

This project is not an isolated layout, but one of the core pillars of Lianyungang Petrochemical's 2026 twin-engine expansion strategy. Another pillar is the total investment of 1.03 billion yuan, planned 30 October 2026 the core logic of the 260000-ton/year aromatics joint treatment project is to further process the low-value by-products from the existing production into high value-added raw materials such as benzene and toluene, so as to realize the re-mining of the value of the stock assets. The two major projects complement each other: aromatics projects tap the potential of the by-product value chain, high-end new materials projects to open up the incremental space, and jointly promote the transformation of Lianyungang Petrochemical from scale expansion to value jump.

Core Tips for Overseas Traders and Supply Chain Practitioners: The commissioning of aromatics projects at the end of 2026 will take the lead in affecting China's import demand for benzene and toluene, and the concentrated release of polyethylene and POE capacity in 2027 will have a greater impact on the global supply and demand balance of related categories. Advance study of China's supply rhythm, assessment of their own product substitution risk, is the key window of the current layout.
