On January 16, the 300,000-ton/year EVA plant (tubular process) and the 100,000-ton/year H-EVA plant (batch process) of Sinopec Guangxi Petrochemical Company began construction at Qinzhou Port in Guangxi. Both plants utilize LyondellBasell’s LUPOTECH technology; the 300,000 tons per year tubular process plant is designed for the large-scale production of photovoltaic-grade EVA, with completion scheduled by the end of December 2027 ； The 100,000 tons per year batch process plant is dedicated to the production of high-end specialty H-EVA products; it is scheduled to be completed by the end of February 2028, with a technical approach that is specifically tailored to meet the demands of the high-end market. The two sets of EVA units are the final pieces in Guangxi Petrochemical’s project for the transformation and upgrading of its refining and chemical production capabilities. The products manufactured will cover key sectors such as photovoltaic encapsulants, high-end cables, foam products, and medical devices. Among them, the photovoltaic-grade EVA products boast industry-leading levels of light transmittance, weather resistance, and cross-linking density, enabling them to meet the requirements for the long-term stable operation of high-efficiency photovoltaic modules. They help fill the domestic gap in EVA materials of high standards for use in photovoltaic encapsulants, reducing reliance on imports, and provide essential material support for reducing costs and improving efficiency while ensuring self-sufficiency in China’s photovoltaic industry. In addition, EVA used in high-end cables boasts excellent temperature resistance, insulation properties, and aging resistance, making it suitable for high-end applications such as new energy vehicles and smart grids ； Foamed products combine light weight, environmental friendliness, and cushioning properties, allowing them to replace traditional materials in high-end packaging and automotive interiors. The mass production of these high-value-added products will further improve China’s supply system for high-end chemical materials, providing strong impetus for the development of strategic emerging industries such as new energy and advanced manufacturing.
