On March 10, 2026, Shanghai, China - Recently, the ethyl silicone oil market has shown strong growth momentum, especially in high-end application fields such as electronics, cosmetics, and new energy industries, where demand continues to rise. According to the latest market research report, the market size of high viscosity ethyl silicone oil in China has reached billions of yuan by 2025, and it is expected to continue to maintain high-speed growth in 2026, with a compound annual growth rate of around 12.5%.


Ethyl silicone oil, as a high-performance organic silicon material, has demonstrated irreplaceable functional value in multiple high-end fields due to its low glass transition temperature, excellent thermal stability, low surface tension, and high volume resistivity. In the field of electronics and electrical engineering, ethyl silicone oil is widely used in semiconductor packaging, LED encapsulation, and 5G thermal interface materials. Its demand has reached 3340 tons by 2025, accounting for nearly 40% of the total market demand.


Cosmetics and personal care are also important application markets for ethyl silicone oil. With the increasing preference of Generation Z consumers for skin sensation experiences such as "soft matte" and "long-lasting makeup", the number of registered cosmetic formulas has exceeded 1800, driving the rapid growth of ethyl silicone oil in this field. In addition, the booming development of the new energy industry has also brought new growth points to the ethyl silicone oil market. In the field of thermal management of power batteries and packaging of photovoltaic modules, ethyl silicone oil has become the preferred material for leading companies such as CATL and Longi Green Energy due to its excellent performance. It is expected that this niche market will exceed 1200 tons by 2026.


The fluctuation of market prices also reflects the supply and demand changes in the ethyl silicone oil market. Starting from the second half of 2024, due to the structural shortage of high-end models, the price of ethyl silicone oil has continued to rise, with a weighted average price of 298000 yuan/ton by 2025. The prices of electronic and cosmetic grade products have significantly increased, reflecting the strong preference of the market for high-purity, narrow molecular weight distribution, and green compliant products.


Industry experts point out that with the iteration of advanced semiconductor packaging technology, upgrading of thermal management for new energy vehicles, and stricter regulation of high-end cosmetic efficacy claims, the ethyl silicone oil market will continue to benefit. However, the industry also faces challenges such as fluctuations in raw material prices, intensified environmental policies, and technological barriers from international giants in the ultra high end market. Therefore, building sustainable competitiveness through intelligent manufacturing, digital supply chain collaboration, and full lifecycle carbon management will become the key to the future development of enterprises.
