In Changxing Island, Dalian, Liaoning, a huge modern factory is quietly changing the industrial landscape of China's high-end new materials industry. With the successful commissioning and stable operation of the main equipment Line 1 of the Dingjide POE high-end new material project with a total investment of 12 billion yuan in October 2025, China has finally ushered in a breakthrough moment of large-scale independent production in the key material field of polyolefin elastomers, which used to rely on imports for a long time. The smooth progress of this project is an important milestone for us to build a national level new materials industry base, demonstrating the strong momentum of transformation and upgrading of the old industrial base in Northeast China, "said the person in charge of the Changxing Island Economic and Technological Development Zone Management Committee

Run construction acceleration in 18 months

The project officially started construction in March 2024 and completed the leap from construction to pilot testing, and then to successful feeding of the main equipment in just 18 months. In June 2025, the pilot plant of the project will be put into operation first; In October of the same year, the main unit Line 1 achieved a successful feeding, and the production operation is currently stable and orderly, becoming the core production line for high-quality POE products.

At the same time, the construction of Line 2 has entered the final stage of construction and is planned to be put into operation in mid January 2026. After the completion of the dual line layout, a strong production capacity synergy will be formed, marking the maturity of Dingji's large-scale production system in the field of new materials. The project commander introduced at the commissioning ceremony, "We have created the 'Dingji Speed' for the construction of similar projects, thanks to the full support of all parties and the scientific scheduling of the construction team

Performance comparable to international standards, with a shipment volume exceeding 5000 tons

At present, the project mainly produces POE modified materials, and its key performance indicators have been strictly tested and have reached the level of international mainstream similar products, achieving a qualitative change from "localization" to "high-quality localization". The product has been sent for sample testing to over a hundred downstream customers and has been recognized by dozens of mainstream manufacturers. As of now, the cumulative shipment volume has exceeded 5000 tons, winning the initial trust of the market with excellent and stable quality, and the import substitution process is accelerating comprehensively. The company's Chief Technology Officer announced at the product launch that "our POE product has reached the international advanced level in key indicators and can fully meet the needs of high-end manufacturing. ”

Build in two phases to solve the bottleneck problem

According to the final investment plan, the total investment of the project is approximately 12 billion yuan, to be implemented in two phases. The first phase mainly involves the construction of a 200000 ton/year POE combined plant, a 300000 ton/year alpha olefin plant, and a 400Nm ³/h electrolytic water hydrogen production plant, which are expected to be put into operation in September 2025. The second phase will construct an additional 200000 tons/year POE combined plant and 250000 tons/year carbonate plant, with plans to put them into operation by the end of 2027. After the project is fully put into operation.

it is expected that the annual operating revenue will reach 11.1 billion yuan, which will effectively solve the bottleneck problem in the high-end new materials field such as POE, fill the domestic gap, and achieve independent guarantee of key materials. The General Manager of Dingjide Petrochemical Technology looks forward to saying, "After the completion of both phases of the project, we will have the strength to compete with international giants and truly achieve independent and controllable high-end new materials."
