Multiple breakthroughs in high-end applications have enabled the industrial chain to collaborate and empower the upgrading of the methyl silicone oil industry

1.The penetration of cutting-edge technology fields is accelerating, and special products are opening up new blue oceans for growth
Methyl silicone oil, with its outstanding physical and chemical properties, is accelerating its entry into high-end technological fields such as aerospace and flexible electronics, becoming a key material support for the application of cutting-edge technologies. In the aerospace field, ultra-low viscosity 5cSt methyl silicone oil has been successfully applied in the lubrication of satellite antenna drive mechanisms and damping fluids for aviation instruments due to its outstanding vacuum stability and wide-temperature damping characteristics. Its evaporation loss is less than 0.01% per 1000h in a high vacuum environment of 10⁻⁶Pa, fully meeting the relevant standards of NASA. In the field of flexible electronics, a technological breakthrough has been achieved in polydimethylsiloxane (PDMS) elastomers based on methyl silicone oil. The self-healing antibacterial electronic skin developed through photopolymerization strategies can achieve an elongation at break of 600% and a self-healing efficiency of 92% within 24 hours at room temperature. It can precisely monitor human movement and provide an innovative solution for the research and development of wearable devices. According to industry estimates, the demand proportion of methyl silicone oil in the high-end technology field has risen to 15% by 2025, and the compound annual growth rate is expected to exceed 20% in the next three years.


2. Optimization of upstream raw material structure and enhancement of core material guarantee capacity
The continuous upgrading of the upstream of the industrial chain has laid a solid foundation for the development of the methyl silicone oil industry, and the stability and self-sufficiency rate of core raw material supply have significantly improved. As a key raw material, metallic silicon has a domestic production capacity accounting for 75% of the global total output. The top five producers have formed a concentrated supply pattern, providing a sufficient basic guarantee for the production of methyl silicone oil. Meanwhile, the industry is accelerating the domestic production research and development of key intermediates such as methylchlorosilane. Through technological iteration and capacity expansion, it is gradually reducing its dependence on foreign sources. Data shows that by 2025, the self-sufficiency rate of core raw materials for methyl silicone oil in China has risen from 65% in 2020 to 78%. Among them, the coverage rate of the self-circulation supply system for metallic silicon and chloromethane exceeds 60%, effectively alleviating the impact of raw material price fluctuations on industry profits. The rational layout of upstream production capacity and technological breakthroughs have led to a 6.3% year-on-year decline in raw material costs compared to 2023, enhancing the market competitiveness of terminal products.

3. The synergy effect of the industrial chain is highlighted, and regional clusters empower high-quality development
The domestic methyl silicone oil industry has formed a multi-regional coordinated development industrial pattern, and the coordinated interaction between the upstream and downstream of the industrial chain has been continuously deepened. Relying on its resource and geographical advantages, the Yangtze River Economic Belt has formed three core industrial clusters in Yichang, Hubei Province, Jiujiang, Jiangxi Province and Zhangjiagang, Jiangsu Province. Together, they contribute 75% of the national production capacity and have achieved a full-chain layout from raw material supply, intermediate product preparation to terminal product production. Enterprises within the region have increased the efficiency of technological research and development by over 30% and shortened the product iteration cycle to 6-8 months by jointly building innovation platforms and sharing logistics resources. Meanwhile, regions such as East China, South China, and Southwest China have formed differentiated development trends. East China focuses on the research and development of high-end special products, South China strengthens application expansion by relying on the daily chemical industry cluster, and Southwest China takes advantage of its energy strengths to develop basic production capacity. The regional synergy effect has further enhanced the overall risk resistance and core competitiveness of the industry.

4. The standard system has been gradually improved, leading the industry to develop in a standardized manner
With the expansion of the industry scale and the upgrading of applications, the industry standard system for methyl silicone oil has been continuously improved, providing strong support for high-quality development. Domestically, a number of specialized standards have been formulated for high-end application fields such as aerospace, medical care, and electronics, including product purity, viscosity control, and biocompatibility. Among them, the standard for methyl silicone oil anti-atomic oxygen erosion coating for aerospace vehicles clearly stipulates the precise control requirements for coating thickness of 50-100nm. Meanwhile, the industry is actively aligning with international standards, promoting the acquisition of relevant international certifications for medical-grade and electronic-grade methyl silicone oil products, and enhancing their global market recognition. The improvement of the standard system not only regulates the market competition order but also guides enterprises to increase investment in the research and development of high-end products, promoting the industry's transformation from "scale expansion" to "quality improvement", laying a foundation for subsequent participation in the global high-end materials market competition.
