The market size of methyl silicone oil is steadily expanding, and the transformation towards high-end products has become the core focus. 

1. Both production capacity and output have increased, and the cluster effect has become prominent.
The actual output of methyl silicone oil in China reached 206,000 tons in 2025, an increase of 5.9% compared to the previous year. While the production capacity has steadily expanded, the industry concentration has continued to rise. The East China region, as the core cluster area, accounted for 58.3% of the national total output. Jiangsu and Zhejiang provinces together contributed over 40% of the production capacity. The South China region, relying on the cluster of end-use application enterprises, accounted for 19.5% and formed an industrial pattern of "main production in East China and application in South China". Although the environmental protection inspections have become stricter, resulting in some enterprises undergoing phased technological renovations and suspending production, the overall industry capacity utilization rate remained at a high level, providing a solid support for market supply. 

2. Downstream demand experiences multiple surges. The new energy sector becomes the growth engine.
The downstream application structure of methyl silicone oil continues to optimize. In 2025, the proportion of the coating and ink fields accounted for 34.2%, making it the largest application market; the demand in fields such as electronic and electrical, textile printing and dyeing, and personal care is also growing simultaneously. The new energy industry has become the core growth driver. The demand for high thermal conductivity methyl silicone oil for battery thermal management has surged due to the high temperature environment, with a 34.6% year-on-year increase in market usage in 2024; the demand for weather-resistant silicone oil in photovoltaic module encapsulation has risen, and the unit price of low-ion-content high-end products is 30%-50% higher than that of ordinary models. In addition, the miniaturization development of electronic devices such as 5G base stations and AI servers has driven the rapid expansion of demand for low viscosity and high purity methyl silicone oil.

3. Price trend remains stable with slight increase. Premium products have significant price premiums.
The average factory price of the mainstream methyl silicone oil models in China in 2025 was 20,480 yuan per ton, increasing by 1.3% year-on-year. The increase was lower than that of the upstream raw materials. The bargaining power of the middle stage was under pressure, but the profit margin remained stable. The product prices showed a significant hierarchical differentiation. The average price of low viscosity (≤100cSt) industrial-grade products was 38.5 yuan per kilogram, that of medium viscosity (100-1000cSt) was 52.3 yuan per kilogram, and that of high viscosity (>1000cSt) reached 74.6 yuan per kilogram, with a price difference of nearly double, highlighting the trend of upgrading towards higher-end products. The price is expected to continue to rise steadily in 2026, and the premium space of high-end products will further expand due to the tight supply and demand situation. 

4. Accelerated Technological Iteration: Green Manufacturing and Domestic Substitution Proceed Simultaneously
The industry's technology has made breakthroughs in the directions of high purity, functionalization, and greenness. The adoption rate of continuous production processes has continued to increase, and unit energy consumption has decreased by approximately 40% compared to traditional processes. The batch stability has been enhanced to 99.8%. The competitiveness of domestic high-end products has strengthened. The metal impurities in high-purity methyl silicone oil have been controlled to below 0.5 ppb, and some products have passed the certification of international high-end customers. At the same time, environmental protection policies have driven the industry transformation. The market share of low VOCs and water-based methyl silicone oil has continued to expand, and the proportion of environmentally friendly products is expected to reach over 45% by 2027.
