Positive news is spreading in the field of organic silicon deep processing. According to the latest research data from Bezos Consulting, the market size of ethyl hydrogen silicone oil in China has reached 274 million yuan in 2024, and the global market size has reached 1.092 billion yuan. It is expected that the global market will increase to 1.865 billion yuan by 2030, with strong growth momentum.


Ethyl silicone oil (polydiethylsiloxane), as one of the core categories, has long occupied traditional markets such as mold release agents, instrument oils, hydraulic oils, and special lubricants due to its outstanding characteristics such as flash point exceeding 265 ℃ (open cup), working temperature range of -60 ℃ to+150 ℃, stable chemical properties, non-toxic and non corrosive properties, and excellent electrical insulation performance.


It is worth noting that aerospace electronic heat dissipation is becoming a new growth pole for ethyl silicone oil. In January 2026, Shenzhen Debon Interface Materials applied for a patent for thermal conductive silicone grease for aerospace electronic equipment. Its core component is ethyl silicone oil with a viscosity of 50-1000 mPa · s, combined with phenyl silicone oil and modified silicone oil, designed to meet the heat dissipation needs of aerospace equipment in extreme space environments.


From the perspective of the industrial chain, the main production capacity of ethyl silicone oil in China is concentrated in Hubei, Jiangsu, Shanghai and other places. Enterprises such as Hubei Qifei Pharmaceutical Chemical and Hubei Chenghai Chemical have achieved mass production of pharmaceutical grade products with a purity of 99% and a supply scale of 10000 kilograms. At the same time, listed companies such as New Yaqiang (603155. SH) have also clearly stated that their ethyl silicone oil products have entered the field of liquid cooled silicone oil and are closely tracking the development of liquid cooling technology.


From "lubrication" to "heat conduction", from ground industry to interstellar exploration - ethyl silicone oil is writing a new chapter in the deep processing of organic silicon with unstoppable momentum.
