Breakthroughs in dimethyl silicone oil technology boost industrial upgrading: heat-resistant and high thermal conductivity products lead new trends————The new modification technology promotes the expansion of application fields, and the market prospects continue to be positive


1. Technological breakthrough: Patent innovation drives the optimization of preparation processes
Recently, domestic enterprises have made remarkable progress in the preparation technology of dimethyl silicone oil. By optimizing the synthesis process, a heat-resistant and highly thermally conductive modified dimethyl silicone oil was successfully developed. Its thermal conductivity was increased to 4-8W/m·K, and the mass loss within 30 minutes at 350℃ was less than 1.0%, significantly enhancing the thermal stability and thermal conductivity of the product. This technological breakthrough stems from the innovative application of raw materials and catalysts, such as the direct synthesis of dimethyldichlorosilane hydrolysate, which eliminates the circular separation step in the traditional process. This not only simplifies the process but also reduces production costs. In addition, the new preparation method achieves targeted regulation of material properties by introducing liquid metal composites and specific catalysts, providing more possibilities for industrial applications.


2. Continuous expansion of application fields: Cross-border applications from cosmetics to electronic products
Dimethyl silicone oil has become a "cross-border star" in multiple fields due to its unique physical and chemical properties. In the field of cosmetics, its low viscosity and lubricity endow skin care products and shampoos with a smoother texture, while reducing the "whitening" phenomenon and enhancing the user experience. In the electronics industry, modified high thermal conductivity silicone oil is widely used in insulating materials and thermal management components, effectively ensuring the stable operation of equipment in high-temperature environments. In addition, its application as a defoamer and excipient in the pharmaceutical field has been continuously deepened, especially playing a significant role in the treatment of flatulence and the preparation of creams. The demand for anti-adhesion in industrial lubrication, building waterproof coatings and food processing has further driven the diversified market demand for dimethyl silicone oil.


3. Broad market prospects: The global scale is steadily growing and prices are stabilizing
According to industry reports, the global dimethyl silicone oil market size is expected to grow from 1.8 billion US dollars in 2023 to 2.9 billion US dollars in 2031, with a compound annual growth rate of approximately 5.8%. The Chinese market has performed particularly well. By 2024, its market size had reached hundreds of millions of yuan. Regions such as East China and South China have become the main growth poles due to their well-developed industrial chains and strong demand. In terms of price, the domestic benchmark price of dimethyl silicone oil has remained stable at around 17,333 yuan per ton recently, and the supply and demand relationship is tending to balance. The drivers of market growth include the demand for high-performance lubricants in the automotive industry, the upgrade of thermal management technology in electronic products, and the continuous increase in the consumption of personal care products.


4. Environmental Protection and sustainable Development: Recycling and technological innovation go hand in hand
With the tightening of environmental protection regulations, the recycling and utilization of dimethyl silicone oil has become a focus of industry attention. Many enterprises have begun to lay out the recycling business of used silicone oil. Through purification and reprocessing technologies, they reapply it in fields such as industrial lubrication and building materials to reduce resource waste. Meanwhile, the direction of technological innovation is focused on developing more environmentally friendly silicone oil formulas, such as using bio-based raw materials or low-toxicity catalysts, in order to reduce carbon emissions and environmental pollution during the production process. In the future, green manufacturing and circular economy models may become new tracks for industry competition.


Conclusion
The technological innovation and market expansion of dimethyl silicone oil not only reflect the progress of materials science, but also reveal the potential for the coordinated development of multiple industries. With the continuous optimization of the preparation process and the continuous expansion of application scenarios, this "industrial blood" is expected to achieve breakthroughs in more high-end fields, injecting new impetus into global industrial upgrading.
