As the wave of new materials industry sweeps across the world, ethyl silicone oil is writing its own brilliant chapter with an unstoppable momentum. The latest industry data shows that the global market for high viscosity ethyl silicone oil has reached approximately 1.87 billion US dollars in 2024, and is expected to increase to 2.12 billion US dollars by the end of 2025, with a compound annual growth rate of about 6.8%. Entering 2026, this momentum is expected to increase instead of decrease - the market size is expected to exceed 2.4 billion US dollars, and the compound annual growth rate will remain stable in the high range of 7% -8%.


China: the undisputed 'main engine'
The Asia Pacific region maintains its position as the largest consumer market with a global market share of 42.3%, and China is the brightest star among them, contributing 68.7% of the total market share in the Asia Pacific region. At present, China has over 35 ethyl silicone oil production enterprises with an annual production capacity of about 62000 tons, accounting for 39.2% of the global total production capacity. The domestic annual demand is about 48000 tons, which not only has a relatively low degree of external dependence, but also has considerable export capacity.


From a regional perspective, the eastern coastal regions continue to lead with a well-established industrial chain and mature market system, while the central and western regions are rising strongly with abundant raw material resources and cost advantages, and their market share is increasing year by year.


Four major application areas support a trillion dollar market
The application scope of ethyl silicone oil is expanding at an unprecedented speed:


Driven by the growth of market share in application fields
Electronic appliances 32.7% 5G communication, AI chip packaging, LED lighting
28.4% building sealing accelerates urbanization process and promotes green buildings
19.6% explosive growth of new energy vehicles in automobile manufacturing
Personal care with 8.3% added value, the highest segmented track
Of particular note is that the rapid development of new energy vehicles is injecting strong power into ethyl silicone oil. It is expected that by 2025, the global sales of new energy vehicles will reach 20 million units, directly driving the annual demand for ethyl silicone oil in the automotive industry to 300000 tons, with a compound annual growth rate of up to 8%. Tesla, BYD and other leading car companies have extensively used ethyl silicone oil in their production processes to enhance vehicle performance and safety.


In the field of semiconductor packaging, ethyl silicone oil also performs outstandingly. According to the International Semiconductor Industry Association, the global consumption of silicone oil for semiconductor packaging in 2024 is about 12000 tons, a year-on-year increase of 11.4%, of which high viscosity ethyl silicone oil accounts for as much as 68.3%. Domestic LED leading companies such as Sanan Optoelectronics and Huacan Optoelectronics extensively use this type of packaging material in their high-end product lines.


Technological Innovation: Moving from Intermittent to Continuous
The underlying logic of industry competition is undergoing profound changes. Continuous production processes are gradually replacing traditional batch production methods, and the successful development of new efficient catalyst systems has significantly improved the selectivity and controllability of polymerization reactions. At the same time, the exploration of replacing traditional chemical synthesis with biocatalytic technology is also accelerating, and greening and high performance have become irreversible industry trends.


In the field of ultra-low temperature, companies such as Xinyuan Chemical have successfully developed ultra-low temperature resistant ethyl silicone oil, which can maintain stable performance under extreme working conditions of -60 ℃, and is widely used in cutting-edge scenarios such as aerospace, polar exploration, and cold chain transportation. New Yaqiang (603155. SH) has explicitly stated that its products such as phenyl silicone oil and vinyl silicone oil can be applied in the field of liquid cooled silicone oil, and is closely tracking the development of liquid cooling technology and making positive progress.


Competition pattern: oligopoly monopoly and domestic substitution in parallel
In the international market, the top five giants such as Dow Chemical, Shinetsu Chemical, and Wacker Chemicals hold about 65% of the market share, building a deep moat in the high-end market. However, domestic enterprises are closing the gap at an astonishing speed - Mount Huangshan Meijia New Materials and Anhui Hecheng Chemical have reached a strategic cooperation in early 2026, striving to achieve import substitution of high-end products by 2027; Runhe Materials plans to issue convertible bonds of no more than 370 million yuan to raise funds for the construction of a high-end organic silicon new material project. After reaching production capacity, it will add 5000 tons/year of electronic grade vinyl silicone oil production capacity.


The golden age of ethyl silicone oil has arrived. Driven by the continuous expansion of the electronics industry, the vigorous development of new energy vehicles, and the flourishing of green buildings, this "super silicone oil" is moving from behind the scenes to the forefront, becoming a key force supporting the high-quality development of China's new materials industry.
