Ethyl silicone oil-based magnetic liquid has emerged, unlocking a new track in special materials

1. Breakthrough innovation has been achieved in modification technology
The technological innovation of ethyl silicone oil has entered a new stage of functional compounding, and ethyl silicone oil-based magnetic liquids have been successfully produced on a large scale. This product uses ethyl silicone oil as the carrier liquid and is combined with nano Fe₃O₄ magnetic particles. Through the "one-step synthesis modification method" process, the average particle size of the magnetic particles is controlled at 8-9nm, with uniform distribution and no agglomeration. Its saturation magnetization can reach 20.0emu/g. Even after being left to stand at -12 ℃ for more than one month, no sediment precipitates out and it maintains good fluidity, far exceeding the stability of traditional mineral oil-based magnetic liquids. The optimized selection of surfactants has further addressed the pain point of easy oxidation in traditional products, significantly enhanced compatibility with ethyl silicone oil, and laid a foundation for applications in special scenarios.


2. Special scenario applications have been fully implemented
The field of precision machinery
With its high compressive resistance similar to that of a "liquid spring", ethyl silicone oil-based magnetic liquid has become an ideal material for shock absorption and vibration reduction in precision instruments. When applied in equipment such as speed measuring machines and synchronous motors, its vibration reduction effect far exceeds that of traditional metal springs. The combination of its excellent lubrication performance and magnetic controllable characteristics can precisely adjust the mechanical friction coefficient, extending the equipment maintenance cycle by more than 50%.


The field of electronics and electrical engineering
Relying on the excellent dielectric properties of ethyl silicone oil, magnetic liquids demonstrate unique advantages in electronic devices in harsh environments. Its dielectric constant is highly dependent on frequency and has extremely low dielectric loss. It can provide insulation protection for electronic components in high-temperature and humid environments. At the same time, it utilizes the magnetic thermal effect to achieve directional heat dissipation, enhancing the operational stability of the equipment.

The field of medical technology
The non-toxic and biocompatible characteristics of this type of product have enabled it to stand out in the medical field. As a magnetic targeting and magnetic sustained-release carrier, it can precisely deliver drugs to the lesion site, improving the treatment efficiency. In the field of magnetic hyperthermia, its excellent thermal stability and magnetic responsiveness provide new material support for minimally invasive treatment.

3. The production process is both highly efficient and environmentally friendly
The preparation process of ethyl silicone oil-based magnetic liquid has significant advantages. It has relatively low requirements for production equipment and mild reaction conditions. Dispersion can be completed simply by heating and stirring at 50-90℃. Environmentally friendly surfactants are used in the production process, which avoids the generation of harmful pollutants. Moreover, the carrier liquid ethyl silicone oil itself is non-toxic and non-corrosive, meeting the standards of green production. The application of automated separation and purification technology has enabled the product purity to reach over 99.5%, while reducing production costs and creating conditions for large-scale promotion.

4. The market prospects for special materials are broad
With the increasing demand for functional composite materials in high-end manufacturing, the market for ethyl silicone oil-based magnetic liquids has entered a period of rapid development. It is expected that in the next five years, the compound annual growth rate of the market size in this niche field will exceed 15%, and the penetration rate in areas such as mechanical seals, electronic packaging, and medical equipment will continue to increase. The combination of the high and low temperature resistance and magnetic properties of ethyl silicone oil will also be extended to high-end fields such as aerospace and new energy, becoming a core growth pole in the field of special materials.
