On December 16, 2025, the 24th China International Organosilicon Materials Exhibition opened in Shanghai, with ethyl silicone oil becoming the focus of the exhibition. The latest technological achievements showcased by multiple companies show that ethyl silicone oil is breaking through traditional application scenarios and accelerating its penetration into emerging fields such as biomedicine, new energy storage, and smart wearables.


Breakthrough in the field of biomedicine
The biocompatibility advantage of ethyl silicone oil has been fully validated in the medical industry. The fluorinated ethyl silicone oil developed by Xinyuan Chemical in collaboration with Shanghai Jiao Tong University has significantly improved its anticoagulant properties by introducing trifluoromethyl groups. It has been successfully applied in the coating of artificial heart valves and vascular stents. Clinical trial data shows that this material can reduce the thrombus formation rate by 80% and shorten the postoperative recovery period of patients by 30%. In addition, the acrylic modified ethyl silicone oil launched by Anhui Aiyota Silicone Oil Co., Ltd. has been used as a lubricant for contact lenses and a filler for medical aesthetics due to its excellent flexibility and transparency, and has received good market feedback.


The demand for new energy storage has surged
Driven by the "dual carbon" goal, the application of ethyl silicone oil in the field of new energy is rapidly expanding. The low viscosity ethyl silicone oil developed in cooperation between Yunnan Energy Investment Silicon Material Technology and Ningde Times can effectively inhibit lithium dendrite growth and improve battery cycle life by 20% as an electrolyte additive for lithium batteries. At the same time, this material can also be used as an encapsulation film for photovoltaic modules. Its UV aging resistance is 5 times higher than traditional EVA materials, which helps stabilize the power generation efficiency of photovoltaic power plants. According to statistics, the demand for ethyl silicone oil in the new energy sector has reached 25% by 2025, becoming the second largest application market after industrial lubrication.


Opening up a new track in the field of smart wearables
The flexible properties of ethyl silicone oil provide a material solution for smart wearable devices. At the exhibition site, a company showcased an ethyl silicone oil-based conductive adhesive film that can achieve seamless bonding between flexible display screens and circuit boards, with a bending radius of up to 1 millimeter, meeting the mass production needs of foldable mobile phones and AR glasses. In addition, modified ethyl silicone oil is also used for the coating of smart watch straps, and its self-healing function can automatically fill scratches and extend the product's service life. Industry experts predict that with the implementation of the metaverse concept, the potential application of ethyl silicone oil in virtual reality devices will be further released.


Accelerating collaborative innovation in the industrial chain
To cope with the technological challenges of cross-border applications, enterprises have strengthened industry university research cooperation. For example, Dongyue Silicon Materials has established a joint laboratory with the Institute of Process Engineering of the Chinese Academy of Sciences to focus on the stability of ethyl silicone oil in extreme environments; Hesheng Silicon Industry has collaborated with Tsinghua University to develop an AI driven silicone oil molecular design platform, reducing the research and development cycle of new products by 60%. At the policy level, the Ministry of Industry and Information Technology has released the "14th Five Year Plan" for the development of the silicone oil industry, which clearly proposes to support the application demonstration of ethyl silicone oil in the high-end field, and provide tax exemptions and research and development subsidies to eligible enterprises.


Future outlook: Technology integration drives value upgrading
With the deep integration of materials science, biotechnology, and information technology, the application boundaries of ethyl silicone oil will continue to expand. Enterprises need to focus on two main directions: functionalization, which endows materials with properties such as conductivity, thermal conductivity, and self-healing through molecular structure design; The second is intelligence, combined with IoT technology to develop responsive silicone oil materials and achieve adaptive environmental regulation. It is expected that by 2028, the market size of ethyl silicone oil in emerging fields will exceed 1 billion US dollars, becoming the core engine driving industry growth.
