On February 6, 2026, Shenzhen, China - With the rapid development of new energy vehicles, 5G communication, and semiconductor packaging, ethyl silicone oil, as a key functional material, is facing a dual opportunity of technological innovation and market expansion. According to authoritative industry institutions, the market size of ethyl silicone oil in China will exceed 6.5 billion yuan by 2025, a year-on-year increase of 22%. Among them, the demand in the high-end field will exceed 40% for the first time, becoming the core driving force for industry growth.


Breakthrough in low-temperature performance and expand application boundaries
Ethyl silicone oil has long been used in fields such as aerospace and power equipment due to its excellent low temperature resistance (below -80 ℃) and electrical insulation properties. However, traditional products are prone to problems such as sudden viscosity increase and decreased fluidity in extreme low temperature environments, which limits their application in ultra-low temperature scenarios.


Recently, a research team announced the successful development of a new type of ultra-low temperature ethyl silicone oil, which maintains stable performance in a wide temperature range of -100 ℃ to 250 ℃ through molecular structure optimization and catalytic system innovation. Experimental data shows that the viscosity change rate of the material at -90 ℃ is reduced by 75% compared to traditional products. It has passed the extreme environment test of polar scientific research equipment and is expected to be applied to the energy system of Antarctic scientific research stations and lubrication components of deep space probes.


This breakthrough has solved the technical problem of difficult equipment start-up in high-altitude regions, "said the technical director of a new energy enterprise." We are collaborating with research institutions to apply ultra-low temperature ethyl silicone oil to wind turbine gearbox lubrication, which is expected to reduce equipment failure rates by more than 30%


The demand for high-end electronic packaging has exploded
The popularization of 5G base stations, data centers, and new energy vehicle charging stations has raised higher requirements for the heat dissipation and insulation performance of electronic components. Ethyl silicone oil is an ideal choice for high-end electronic packaging materials due to its low dielectric constant, high thermal conductivity, and chemical stability.


According to calculations, the amount of thermal conductive material used in a single 5G base station has increased by 2.8 times compared to 4G, driving the annual growth rate of demand for ethyl silicone oil in the communication field to exceed 25%. At the same time, the new energy vehicle charging module requires a high voltage resistance performance of silicone oil of over 10kV, which has prompted the industry to accelerate the development of high-purity and low impurity products.


We use nanoscale filtration technology to control the metal ion content in silicone oil below 0.05ppm, meeting the requirements of chip level packaging. ”Experts from a certain research and development institution revealed that "the material has passed certification tests by multiple leading companies and is expected to achieve large-scale supply in the second quarter of 2026


Environmental policies are forcing industrial upgrading
With the advancement of the "dual carbon" target, the ethyl silicone oil industry is facing stricter environmental constraints. In traditional production processes, the emission of by-products such as hexamethyldisiloxane (MM) has long plagued enterprises. In 2025, the Ministry of Ecology and Environment issued the "Emission Standards for Pollutants in the Organic Silicon Industry", requiring a 40% reduction in wastewater discharge per unit of ethyl silicone oil production compared to 2023.


In response, leading companies in the industry have invested in green technology research and development. A certain enterprise achieved a MM recovery rate of over 98% and a 15% reduction in energy consumption per ton of product through closed-loop production process transformation; Another company has developed bio based ethyl silicone oil to replace some petroleum based raw materials with renewable resources, reducing carbon footprint by 30%.


Environmental protection is not a cost burden, but a catalyst for technological innovation, "said the head of an industry association." By 2025, the proportion of environmental protection investment in the industry has reached 8% of revenue, and it is expected to form a billion dollar green silicon material market by 2028
