On February 13, 2026, significant progress was made in the field of organic silicon materials in China: a new type of high-temperature resistant ethyl silicone oil composite material was successfully applied to the heat dissipation system of 5G base stations, solving the industry problem of traditional silicone grease being prone to volatilization and thermal conductivity degradation in extreme environments. This material was jointly developed by a national laboratory and multiple research institutions over a period of three years. Through molecular level modification technology, the temperature resistance threshold of ethyl silicone oil was increased to 300 ℃, and the thermal conductivity was optimized to 1.8 times the industry average level.


In a test conducted by a 5G equipment manufacturer in Shenzhen, the use of this material in the heat dissipation module reduced the temperature of the core chip of the base station by 12 ℃, reduced energy consumption by 8%, and effectively extended the service life of the equipment. The project leader pointed out that traditional silicone grease has stable performance in the temperature range of -40 ℃ to 150 ℃, but 5G base stations often face high temperatures in deserts or polar regions. The new ethyl silicone oil achieves wide temperature range applicability from -60 ℃ to 300 ℃ by introducing a fluorinated chain segment structure. ”


Industry data shows that by 2025, the global construction scale of 5G base stations will exceed 12 million, and the demand for high-performance heat dissipation materials will grow at an average annual rate of 23%. This technological breakthrough marks China's breaking of foreign monopolies in the field of high-end electronic thermal conductivity, and related patents have entered the international PCT application stage. The environmental protection department has simultaneously disclosed that the production process of this material adopts a closed-loop catalytic process, which reduces volatile organic compound (VOCs) emissions by 76% compared to traditional processes and meets the latest requirements of the EU REACH regulation.
