Phenyl silicone oil leads the upgrade of high-end materials, and domestic technological breakthroughs empower emerging industries. 

1.Performance Upgrade: From Ordinary Silicone Oil to Special "Liquid Gold"
Phenyl silicone oil, as the premium category of organic silicone materials, achieves a comprehensive performance upgrade through molecular structure optimization. Compared to ordinary methyl silicone oil, its thermal stability has significantly improved, with a long-term usage temperature exceeding 300℃, short-term temperature resistance exceeding 380℃, and maintaining good fluidity even at low temperatures, with a minimum working temperature as low as -70℃. Additionally, the product possesses excellent radiation resistance, high insulation, and high refractive index properties. Its radiation resistance performance is enhanced by 3 times compared to ordinary silicone oil, with the γ-ray tolerance exceeding 10⁶Gy, making it an indispensable key material in aerospace, nuclear energy, and electronics fields.

2. Market Expansion: Steady growth in scale and accelerated domestic substitution
The market size of phenyl silicone oil in China reached 15 billion yuan in 2025, with a year-on-year growth of 10.2%. It is expected to further expand to 16.53 billion yuan in 2026, maintaining a stable upward trend. The industry development shows a structural optimization, with the domestic self-sufficiency rate continuously increasing. In 2025, it reached 92.7%, an increase of 2.6 percentage points compared to 2024, and the import volume decreased by 8.9%. The downstream demand is concentrated in four major fields: electronic packaging, new energy vehicles, aerospace, and high-end cosmetics. In the electronic packaging field, the consumption volume reached 64,000 tons in 2025, with an output value exceeding 7 billion yuan, becoming the largest application market. 

3. Technological breakthrough: Customization and high-endization become the mainstream direction
Currently, the phenolic silicone oil industry is deeply evolving towards higher purity, narrower distribution, and functionalization. Products with high phenolic content (5-30 mol%), high monomer purity (≥99.98%), and low volatile components have become the mainstream in the market. For different application scenarios, customized products are rapidly evolving: In the field of new energy, efficient thermal conductive products with a thermal conductivity of 0.2 W/m·K have been developed, helping to increase the heat dissipation efficiency of 5G base stations and battery power supplies by 40%; In the cosmetics field, high-purity (≥99.95%) and low-ring body (D4 + D5 ≤ 10 ppm) products have been launched to meet the latest safety standards requirements. 


4. Green Transformation: Sustainable Development Redefines Industrial Ecology
With increasingly strict environmental policies, the production of phenyl silicone oil is accelerating its transition towards green and low-carbon. Industry enterprises are actively promoting solvent-free process and low-VOC emission technology transformation. By 2025, large-scale enterprises within the industry will basically complete the upgrade of RTO waste gas treatment facilities. At the same time， breakthroughs have been made in the research and development of environmentally friendly phenyl silicone oils with better biocompatibility and degradability. These products are widely used in disposable medical supplies and high-end skincare products， promoting the sustainable development of the entire industrial chain. It is expected that in the next three years， the market share of green and environmentally friendly phenyl silicone oil will increase from the current 35% to over 50%.
