Domestic High-End Material Breaks Through Again! 100,000 Tons/Year High-End Hot Melt Adhesive Grade HEV Facility Officially Completed

On September 28th, Jiangsu Hongjing New Material Co., Ltd. officially handed over its 100,000-ton/year high-end hot melt adhesive grade ethylene-vinyl acetate copolymer (HEV) unit.

The Jiangsu Hongjing 100,000-ton/year HEV project is located in the Xuwei New District of Lianyungang City, Jiangsu Province, with a total investment of approximately 2 billion yuan. It is a key project in the region focusing on high-end chemical materials. The project introduces the internationally advanced ECI kettle method process technology package, and upon completion, it will fill the domestic supply gap for high-end hot melt adhesive-grade HEV capacity.

On September 7, 2022, the groundbreaking ceremony for the Dongfang Shenghong Chemical New Materials Project was held at the Lianyungang Petrochemical Base. The Shenghong Chemical New Materials Project has a total investment of 21.6 billion yuan and is planned to produce 700,000 tons of EVA, 50,000 tons per year of copolymer new materials, as well as projects for PO/SM and polyols.

The Shenghong New Materials Project is divided into two parts: Hongwei and Hongjing.

The Hongwei section: Invested and constructed by Jiangsu Hongwei Chemical Co., Ltd., includes a POSM project, with the construction of a 508,000 tons/year ethylbenzene unit, a 200,000/450,000 tons/year POSM unit, a 112,500 tons/year PPG unit, and a 25,000 tons/year POP unit.

The Hongjing section: Invested and constructed by Jiangsu Hongjing New Material Co., Ltd., with a total investment of approximately 15.58 billion yuan, covering an area of about 1395 mu. It includes the construction of facilities with an annual production capacity of 3×200,000 tons of photovoltaic-grade ethylene-vinyl acetate copolymer (EVA), 100,000 tons of high-end hot melt adhesive-grade ethylene-vinyl acetate copolymer (EVA), high-end copolymer new materials, as well as utilities and auxiliary facilities.

As the core layout focusing on high-end chemical materials in Xuwei New District, this project has a total investment of 2 billion yuan. The main plant area covers 49,410 square meters, and the supporting finished product and packaging warehouse covers 18,900 square meters, ranking among the top in the country for similar installations. To tackle the technical challenges of high-end HEV production, the project introduces the internationally leading ECI kettle process technology package. By directly injecting cold ethylene into the cooling system, it achieves uniform product cooling, thereby preventing crystalline spots and fisheye defects from the source. Additionally, with an operating pressure range of 280 MPaG, it can produce high-end products with a narrower molecular weight distribution. The process safety has been verified by over 50 years of global industrialization.

This technology choice precisely aligns with the demands of the domestic market—currently, there is a long-term supply gap in the high-end HEV capacity in China's hot melt adhesive sector, and the overall import dependency of EVA materials has been over 50%. After the commissioning of this facility, it will effectively fill the market void and alleviate the "choking point" dilemma.

From pile foundation construction to the equipment handover, the project team achieved the implementation of all cycle milestones through precise management.

The Jilin Mengxi supervision unit and all participating subcontractors work together throughout the process, adhering to strict standards to control project quality, providing strong support for the high-quality advancement of the project.

Under the dual drive of the "dual carbon" strategy and the upgrading of the manufacturing industry, China's demand for high-end chemical materials continues to rise. This project is an important layout of Shenghong Petrochemical Industry Group in the high-end EVA field, forming a synergistic effect with the integrated refining and chemical base in the region, further improving the high-end chemical materials industry chain in East China. Currently, East China occupies a core share of the country's total EVA consumption, with high-end application demands such as hot melt adhesives concentrated in the area. After the project is put into production, it will achieve efficient matching of "production to sales" in the region.

With the advancement of subsequent production preparations, the facility is expected to quickly enter a stable operating phase, providing domestic high-end raw material guarantees for downstream industries such as automotive, packaging, and electronics, contributing to China's accelerated transition from a "chemical giant" to a "material powerhouse."
