On September 26, 2025, Beijing - At the "Extreme Environmental Materials Technology Seminar", the innovative application of ethyl silicone oil in deep-sea exploration, aerospace and other fields became the focus. A specially modified ethyl silicone oil is becoming a "protective shield" for critical equipment in extreme environments due to its excellent pressure resistance, radiation resistance, and low-temperature fluidity.


Deep sea exploration: stable performance under 10000 meters of water pressure
In response to the strict requirements of lubrication materials for deep-sea exploration equipment, the research team has developed ethyl silicone oil that can maintain lubrication performance at a water pressure of 11000 meters by adjusting the molecular chain length and side structure of silicone oil. In the recent Mariana Trench experiment, the deep-sea robotic arm equipped with this material completed 30 consecutive days of fault free operation, with a lubrication film thickness attenuation rate of less than 5%.
Traditional mineral oil deteriorates rapidly under high pressure, while the stability of ethyl silicone oil provides reliable guarantees for deep-sea operations, "said an engineer from the National Deep Sea Base Center." In the future, this material is expected to be applied in fields such as manned submersibles and underwater mineral mining equipment


Space Journey: Radiation Resistant Coating Protects Spacecraft
In the aerospace field, ethyl silicone oil also demonstrates unique advantages. A modified silicone oil with rare earth elements added can form a dense anti radiation coating, effectively blocking the damage of cosmic rays to spacecraft electronic components. In simulated space environment tests, solar panels coated with this material showed a 70% decrease in efficiency decay rate compared to uncoated materials after 1000 hours of continuous radiation.
From low Earth orbit to deep space exploration, the radiation resistance of materials directly determines the lifespan of spacecraft, "said a material expert from China Aerospace Science and Technology Corporation." The lightweight and high adhesion properties of ethyl silicone oil coating make it an ideal choice for the next generation of spacecraft


With the increasing demand for extreme environmental exploration, the application boundaries of ethyl silicone oil are constantly expanding. Industry insiders predict that by 2030, its market share in deep sea, space and other fields will increase to 25% of the overall market, becoming a key driving force for the advancement of high-end material technology.
