March 24, 2026, Shanghai, China - In recent years, with the rapid development of new energy vehicles, photovoltaic industry, and high-end electronic equipment, the market demand for ethyl silicone oil as a high-performance silicone material continues to rise, and the market size is expected to achieve significant growth in the coming years. According to the latest "2026 China Ethyl Hydrogen Silicone Oil Data Monitoring and Research Report" released by authoritative research institutions in the industry, the market size of ethyl silicone oil in China has reached about 8.5 billion yuan by 2025, and is expected to grow to 10.2 billion yuan by 2026, with a compound annual growth rate of 14.8%.


Ethyl silicone oil, also known as polydiethylsiloxane, is a type of polysiloxane polymer that replaces methyl with ethyl. It has excellent high and low temperature stability, lubrication performance, and electrical insulation performance. Its working temperature range is wide, from -60 ℃ to 150 ℃, and its temperature viscosity coefficient is small, which enables ethyl silicone oil to maintain stable performance in extreme environments. In addition, ethyl silicone oil also has good chemical inertness and weather resistance, and is not easily reacted with acids, bases, oxidants, etc. Therefore, it is widely used in various fields such as precision instrument lubrication, electronic insulation, cosmetic thickening, pharmaceutical excipients, etc.


In the field of new energy vehicles, ethyl silicone oil is a key component of battery coolant and lubricating oil, and its demand is rapidly increasing with the expansion of the new energy vehicle market. Especially in high-temperature environments, ethyl silicone oil can effectively reduce battery temperature, improve battery performance and safety, and become the preferred material for new energy vehicle manufacturers.


In the photovoltaic industry, ethyl silicone oil, as a packaging material and backplate material for photovoltaic modules, has excellent weather resistance and waterproof performance, which can significantly improve the service life and power generation efficiency of photovoltaic modules. With the increasing global demand for clean energy, the photovoltaic industry has entered a period of rapid development, and the market demand for ethyl silicone oil has also skyrocketed.


In the field of high-end electronic devices, ethyl silicone oil plays an important role as a heat dissipation material and insulation medium in consumer electronics products such as smartphones, tablets, and laptops. With the popularization of technologies such as 5G and the Internet of Things, electronic devices have increasingly high requirements for heat dissipation and insulation performance, and the market demand for ethyl silicone oil will continue to grow.


Faced with the vast market prospects, domestic ethyl silicone oil production enterprises have increased their research and development investment to improve product quality and technological level. Taking Mount Huangshan Meijia New Material Co., Ltd. and Anhui Hecheng Chemical Co., Ltd. as examples, the two enterprises announced at the beginning of this year that they had reached a strategic cooperation to jointly layout the field of electronic grade vinyl silicone oil, aiming to overcome the technical bottleneck of high-end electronic grade silicone oil and achieve import substitution. By integrating the superior resources of both parties in the field of synthetic material manufacturing and fine chemical industry, Mount Huangshan Meijia and Anhui Hecheng will launch an impact on high-end application markets such as semiconductor packaging, new energy vehicles, optical devices, and promote the development of ethyl silicone oil industry towards high-end and fine direction.
