Since 2026, the domestic field of organic silicon special materials has ushered in a new round of growth boom. According to the latest industry statistics, the global market size of high viscosity ethyl silicone oil has exceeded 2.1 billion US dollars, with the Asia Pacific region firmly occupying the world's largest consumer market with a 42.3% share. Among them, the Chinese market contributes nearly 70% of the demand in the Asia Pacific region. As an important organic silicon production cluster in China, Anhui Province has recently launched new projects in the field of special silicone oil. The strategic cooperation project between Mount Huangshan Meijia and Anhui Hecheng Chemical is accelerating the construction of electronic special silicone oil production lines, providing new industrial support for the localization of high-end products such as ethyl silicone oil.


Ethyl silicone oil, with its excellent low-temperature resistance, can maintain stable fluidity in extreme environments of -70 ℃, far exceeding the lower limit of use of ordinary methyl silicone oil at -50 ℃. It is an indispensable key material for special scenarios such as aerospace, polar equipment, and new energy wind power. At present, there are more than 35 high viscosity ethyl silicone oil production enterprises in China, with a total annual production capacity of 62000 tons, accounting for 39.2% of the global total production capacity. They can not only meet the domestic market demand of 48000 tons per year, but also have stable export capacity, and their external dependence has been reduced to a relatively low level.


With the gradual replacement of traditional intermittent production mode by continuous production technology and the widespread application of new high-efficiency catalysts, the controllability of polymerization reaction of domestic ethyl silicone oil products has been greatly improved, and the profit margin of high-end product lines can reach over 28%. Recently, new material industrial parks in Anhui Bengbu and other places have also accelerated the layout of the special silicone supporting industry chain, relying on the synergy advantages of the Yangtze River Delta industry to promote the application and landing of ethyl silicone oil in emerging scenarios such as 5G communication packaging and energy storage system insulation, further improving the industrial layout of special silicone oil in East China.
