On August 21, 2026, significant progress was made in China's ethyl silicone oil industry. Leveraging the technological expertise of domestic enterprises such as Anhui Mingyi Silicon Industry, coupled with collaborative efforts from Anhui's new materials sector, the core production process of electronic-grade ethyl silicone oil has achieved substantial breakthroughs. Previously, the global high-end ethyl silicone oil market was long monopolized by international giants like Dow Chemical and Shin-Etsu Chemical, leaving domestic downstream sectors—such as semiconductor packaging and insulation components for new energy vehicles—reliant on imports for high-end demand. This not only kept procurement costs high but also resulted in delivery cycles exceeding six months.


The Anhui enterprise joint research team focused on addressing two major industry pain points—metal ion residues and viscosity stability in electronic-grade products—through technological advancements. By introducing a comprehensive ICP-MS detection system, they successfully reduced the total sodium and potassium ion content in the product below 0.5ppm and stabilized inter-batch viscosity fluctuations within ±3%, fully meeting the electronic material application standards of the JEDEC Solid State Technology Association. Industry research data indicates that domestic ethyl silicone oil production capacity reached 62,000 tons in 2026, accounting for 39.2% of global total capacity. With the implementation of this advanced process, the delivery cycle for domestically produced high-end ethyl silicone oil can be shortened to 7-15 days, while procurement costs are approximately 22% lower than imported counterparts. This will directly benefit the supply chain stability of emerging industries such as 5G communications, photovoltaic energy storage, and AI chip packaging and testing.


Industry experts noted that the domestic ethyl silicone oil sector had long been dominated by general-purpose products, mired in a price war with overall profit margins hovering around 15%. In contrast, high-end modified ethyl silicone oil can achieve profit margins of over 28%. This technological breakthrough by Anhui-based enterprises marks a pivotal shift in China's ethyl silicone oil industry—from a "scale-driven" capacity competition to a high-quality development phase focused on "purity and scenario adaptability." It is projected that by 2027, the market penetration of domestically produced high-end ethyl silicone oil will rise from less than 10% to 40%, further advancing the domestic silicone industry chain toward higher-value-added segments.
