In 2026, with the rapid development of downstream industries such as new energy, semiconductors, and personal care in China, the application boundaries of ethyl silicone oil are constantly expanding. Ethyl silicone oil, which was only used as a special lubricating material in the past, has now penetrated into multiple high value-added fields such as thermal conductivity media, cosmetic raw materials, and pharmaceutical intermediates, and the market demand is showing a diversified and explosive trend.


For a long time, the application of ethyl silicone oil has mainly focused on three traditional fields: electronics and electrical appliances, building sealing, and automobile manufacturing, which together account for nearly 80% of the market share. But since the beginning of this year, the explosive growth of the new energy industry has opened up a new growth curve for ethyl silicone oil: in the extreme cold area operation and maintenance scenarios of photovoltaic power plants, ethyl silicone oil has become the core lubricating material for tracking bracket bearings with excellent low-temperature resistance, and can work stably for a long time in an environment of -65 ℃, greatly reducing the operation and maintenance costs of photovoltaic power plants in high-altitude areas; In the temperature control module of energy storage systems, modified ethyl silicone oil serves as a new type of thermal conductive medium that combines insulation and chemical stability, perfectly adapting to the wide temperature range temperature control needs of energy storage batteries. In the first half of this year, the demand for ethyl silicone oil in this field increased by over 60% year-on-year.


At the same time, the personal care and pharmaceutical fields are becoming the emerging tracks with the highest added value of ethyl silicone oil. As ethyl silicone oil has low volatility, low surface tension and no irritation to the skin, the purified cosmetic grade ethyl silicone oil has now been widely added to high-end face cream and hair care products, which can bring a silky and non greasy feeling to skin care products. This year, the market size of this segment has increased by 35% year-on-year. In the field of pharmaceutical intermediates, high-purity ethyl silicone oil has become a key additive for some sustained-release drugs due to its stable chemical inertness, and the market premium of related products far exceeds that of industrial grade products.


From the perspective of the global market landscape, the Asia Pacific region currently holds 42.3% of the global market share for ethyl silicone oil, while the demand in the Chinese market accounts for 68.7% of the total in the Asia Pacific region, making it the most core consumer market in the world. With the stable mass production of domestic full viscosity range ethyl silicone oil products, the high viscosity special ethyl silicone oil that relied on imports in the past has now achieved complete independent supply, and the overall external dependence of the domestic market has dropped to below 15%. Some high-performance products have also begun to be exported in bulk to North American and European markets. Industry forecasts show that the global market size of ethyl silicone oil is expected to exceed 2.4 billion US dollars by 2026, and the contribution of the Chinese market will further increase. With the continuous expansion of downstream emerging scenarios, the entire industry will maintain a compound annual growth rate of over 7% in the next three years.
