Core Performance and Technical Indicators

1. Wide temperature stability: The product has a wide viscosity range, from 5 cps to 2 million cps, and can be used long-term in environments ranging from -50°C to +200°C. In the absence of air or in an inert gas, the long-term use temperature can reach above 200°C. The viscosity-temperature coefficient is small, and the viscosity fluctuation with temperature change is minimal, superior to most mineral oils.
2. Excellent physical and chemical properties: It has outstanding chemical stability and is non-corrosive to metals except for alkali; it has low surface tension (15.9~21.5 dynes/cm), good spreadability, water repellency, moisture resistance, high volume resistivity (10¹⁴~10¹⁶ ohm·cm), and its dielectric properties are minimally affected by temperature and frequency. In addition, it features physiological inertness, non-toxicity, tastelessness, and 100% light transmittance.
3. Main application fields
   • Electronics & Electrical: Used as transformer oil, insulating impregnating liquid, damping oil, and moisture-proof protective coating for electronic components.
   • Industrial Production: Used as a release agent, isolating agent, and brightener for rubber, plastics, and polyurethane products; lubricating oil and damping oil for machinery and instruments.
   • Textiles & Daily Chemicals: Used as a fabric softener and hand feel improver; lubricating additive for skincare creams and shampoos, providing a silky feel.
   • Other Fields: Paint antifoaming agent, leather brightener, polishing oil additive, etc.

Industry Development Trends

1. Steady expansion of market size: The global dimethyl silicone oil market size in 2024 is approximately 667 million US dollars, and it is expected to grow to 784 million US dollars by 2031, with a compound annual growth rate of about 2.4%. The growth rate of the Chinese market is significantly higher than the global average; the market size is expected to exceed 8 billion yuan in 2025 and reach 12 billion yuan by 2030, with a compound annual growth rate of about 10%.
2. Growth in demand from high-end application fields: With the miniaturization and high-efficiency of electronic devices and the development of the new energy vehicle industry, the demand for electronic-grade and medical-grade high-purity dimethyl silicone oil has surged. Especially in the fields of semiconductor packaging, medical device lubrication, and new energy battery thermal management, products are required to have lower volatile content, lower ion content, and higher thermal stability.
3. Green manufacturing and process upgrading: Environmental protection policies are driving the industry's transformation towards green production processes. In 2023, the comprehensive energy consumption per 10,000 yuan of industrial output value decreased by 9.7% year-on-year. In the future, solvent-free and low-energy continuous production will become the mainstream. Meanwhile, research on bio-based silicone sources and biodegradable modifications is also gradually advancing to meet the needs of sustainable development.
4. Accelerated domestic substitution: Through technological innovation, domestic enterprises have achieved a catch-up with international giants in the field of high-end dimethyl silicone oil. Relying on the advantages of a complete industrial chain and cost, the market share of domestic products in the domestic market continues to rise, and they are gradually expanding into overseas markets.
