On April 9, 2026, Shanghai, China - With the continuous expansion of the global silicone market, ethyl silicone oil, as an important sub sector, is ushering in unprecedented development opportunities. According to the latest market research report, the global market size of high viscosity ethyl silicone oil has reached about 1.87 billion US dollars in 2024, and it is expected to exceed 2.4 billion US dollars by 2026, with a high compound annual growth rate of 7-8%.


Ethyl silicone oil, also known as polydiethylsiloxane, is widely used in various fields such as electronics and electrical appliances, building seals, and automotive manufacturing due to its excellent lubricating properties, dielectric properties, and chemical corrosion resistance. Especially in the field of electronic appliances, ethyl silicone oil, as a key material in integrated circuit packaging, LED lighting devices, and power capacitors, is experiencing a surge in demand with the rapid development of emerging industries such as 5G communication and new energy vehicles.


Due to its unique physical and chemical properties, high viscosity ethyl silicone oil is irreplaceable in high-end applications, "said an industry analyst." With the continuous improvement of product performance requirements in downstream application markets, the market demand for high viscosity ethyl silicone oil will continue to grow


As the world's largest producer and consumer of ethyl silicone oil, China has over 35 production enterprises with an annual production capacity of approximately 62000 tons, accounting for 39.2% of the global total production capacity. Domestic enterprises such as Zhejiang Xin'an Chemical and Jiangxi Blue Star Spark Organic Silicon are gradually improving their market competitiveness through process optimization and cost control. Some enterprises have the ability to replace imported products in specific niche areas.


However, with the intensification of market competition, the ethyl silicone oil industry is also facing challenges such as fluctuations in raw material prices and tightening environmental policies. Industry insiders suggest that companies should increase investment in technological innovation, develop high-performance and environmentally friendly products to meet changes in market demand, and strengthen industry chain collaboration to enhance overall profitability.
