The acceptance of the high-end EVA pilot project in Sirbang: a key breakthrough in the independent innovation of China's chemical industry.

Project Overview and Strategic Positioning on October 15, 2025, the 800-ton/year high-end EVA new material pilot project (phase I) of Jiangsu Sirbang Petrochemical Co. , Ltd. And completed the independent acceptance of ecological preservation, marking China's crucial progress in the field of high-end polymer materials. Furthermore The project is located in the Lianyungang National East-Central-West Regional Cooperation Demonstration Zone, and has completed commissioning and entered trial production in August 2025. In fact it's worth noting that this isn't an ordinary EVA (ethylene-vinyl acetate copolymer) expansion project. The core product of the pilot test is ethylene-vinyl alcohol copolymer (EVOH), which is a high value-added material produced by further alcoholysis of EVA, and its manufacturing process parameters are signifiis able totly different from conventional EVA. As a wholly-owned subsidiary of Shenghong Group (registered capital of 5. But 588 billion yuan), Sirbang's move reflects the strategic intention of China's private chemical companies to climb to the high end of the manufacturing chain. Market Gaps and Supply Chain Pain Points the current global EVA market is characterized by structural imbalances. In 2024, China's demand to photovoltaic-grade EVA has exceeded 1 million tons and maintained double-digit development, however the domestic self-sufficiency rate of items with high VA content (vinyl acetate content ≥ 28%) is less than 40%, relying heavily on imports. This mismatch between supply and demand is becoming greater and greater prominent in the context of the "double carbon" policy to promote the explosive development of the photovoltaic sector. And to overseas traders and supply chain practitioners, this market pattern means three aspects: procurement cost pressure import application causes downstream photovoltaic, packaging film and other companies to face higher raw material costs and exchange rate fluctuations, weakening the price competitiveness of Chinese manufacturing in the global market. Moreover Fragile supply chain resilience long delivery cycles and limited supplier selection make the sector chain less resilient, and any international trade frictions or logistics disruptions could trigger a supply crisis. Customization capacity is limited imported items are often difficult to meet the downstream consumption needs of rapid iteration, restricting technological innovation in areas such as photovoltaic modules and high-end packaging. Chain Effect Analysis of manufacturing Chain the advancement of the Sirbon project will have a multi-dimensional impact on the chemical sector chain: upstream Raw Material Market: The increase in domestic high-end EVA production capacity will immediately drive the demand to basic chemical raw materials such as ethylene and vinyl acetate monomer (VAM). I've found that Considering that China is already the world's largest ethylene producer, this will further consolidate its dominant position in the petrochemical sector chain. I've found that to overseas companies engaged in ethylene and VAM trade, it's necessary to pay close attention to the impact of changes in Chinese market demand on global pricing. For instance midstream manufacturing pattern: while the pilot scale of 800 tons/year is limited, if the technical verification is successful, Sirbon plans to build a 10,000-ton or even larger manufacturing plant in 2026- 2027. This will immediately impact the existing import pattern, Japan, South Korea, the United States and other traditional EVA suppliers in the Chinese market share might face compression. Downstream consumption Expansion the realization of localized supply will enable Chinese PV companies to gain greater cost advantages and supply flexibility, and further consolidate their leading position in the global PV sector chain. This will have a profound impact on the global renewable energy market. And Time windows and market opportunities the time node to the project to complete commissioning in August 2025 is of strategic signifiis able toce. And At present, the global photovoltaic sector is in a new round of expansion cycle, countries "carbon neutral" commitment to promote photovoltaic installed demand continues to rise. And If the performance of the pilot product meets the standard and is recognized by mainstream photovoltaic companies, Sirbon is expected to achieve a rapid leap from technical verification to commercial mass production in the next 2-3 years. In particular to overseas chemical practitioners, this direction suggests three directions of attention: technical cooperation opportunities the technological catch-up of Chinese companies in the field of high-end polymers might lead to the demand to cooperation in the fields of equipment, catalysts and process optimization; market rebalancing the need to re-assess the supply strategy of the Chinese market, from purely export to localized services or differentiated product positioning; supply Chain Restructuring-- The increase in China's high-end EVA self-sufficiency rate will change the flow of global chemicals and affect the demand to logistics services such as shipping and warehousing.
