In November 2025, driven by the global carbon neutrality goal, ethyl silicone oil, with its environmental characteristics and multifunctionality, will usher in a green revolution in the fields of building energy conservation, photovoltaic packaging, and intelligent building materials, becoming a key material for urban low-carbon transformation.


Invisible Champion of Building Energy Efficiency
In the ultra-low energy consumption building, ethyl silicone oil, as the core component of aerogel insulation felt, has reduced the thermal conductivity of traditional insulation materials from 0.03W/(m · K) to 0.012W/(m · K), realizing the technical breakthrough of "zero energy consumption building". After the application of ethyl silicone oil gas gel composite thermal insulation system in Shanghai center Building, the heating energy consumption in winter has been reduced by 55%, and the annual carbon reduction has exceeded 2000 tons. In addition, ethyl silicone oil-based waterproof coating extends the waterproof life of building exterior walls to 25 years and reduces maintenance carbon emissions by 40% by forming a dense hydrophobic film.


The photovoltaic industry is a powerful tool for increasing efficiency
In the field of photovoltaic module packaging, ethyl silicone oil, as an organic silicone adhesive, significantly improves the anti PID (potential induced decay) performance of solar cells. The "double-sided power generation specific ethyl silicone oil adhesive film" developed by a leading photovoltaic enterprise reduces the attenuation rate of module output power from 3% to 0.5%, and achieves an annual power generation gain of 5%. By 2025, the global installed capacity of photovoltaics will exceed 500GW, driving a 60% increase in demand for ethyl silicone oil in the photovoltaic field. Chinese manufacturers will occupy 70% of the global market share.


Innovative application of intelligent building materials
The self-healing concrete developed by combining ethyl silicone oil and graphene can automatically release silicon oxygen bonds to repair cracks when they appear, extending the service life of building structures to 100 years. After adopting this technology, the maintenance cost of a landmark project in Shenzhen has been reduced by 80%. At the same time, the transparent conductive film based on ethyl silicone oil realizes the integration of "power generation and dimming" of building glass. After its application in a certain office building, the annual power generation meets 20% of its own electricity demand and reduces air conditioning energy consumption by 15%.


Dual wheel drive of policy and market
The "14th Five Year Plan for Building Energy Efficiency and Green Building Development" of the Ministry of Housing and Urban Rural Development of China clearly states that by 2025, new urban buildings will fully implement green standards, and low-carbon materials such as ethyl silicone oil will be included in the key promotion catalog. According to calculations, if all new buildings in China adopt ethyl silicone oil based energy-saving systems, it can reduce carbon emissions by 120 million tons per year, equivalent to planting 6 billion trees. In terms of the capital market, the average increase of A-shares' ethyl silicone oil concept stocks in 2025 will reach 120%, and institutions predict that the global market size of ethyl silicone oil for green buildings will exceed 1.5 billion US dollars by 2026.


Experts suggest that enterprises need to accelerate the research and development of ethyl silicone oil recovery and regeneration technology, and establish a "production use recovery" closed-loop system to cope with future trade barriers such as EU carbon tariffs.
