The breakthrough in phenyl silicone oil technology has accelerated the process of upgrading high-end manufacturing and domestic substitution


1.The extreme environment resistance performance has reached a new high, meeting the demands of high-end applications
The latest research shows that phenyl silicone oil has made a major breakthrough in temperature resistance, and its working temperature range has been expanded to -70 ℃ to 380℃. This material, through molecular structure optimization, can maintain fluidity in ultra-low temperature environments and does not experience performance degradation over long-term use at high temperatures. For instance, in the aerospace field, a certain type of phenyl silicone oil was tested in the sealing system of a rocket engine, continuously withstanding a temperature of 300℃ and a pressure of 15MPa for over 1,000 hours, with its performance remaining as stable as before. In addition, its radiation resistance has also been significantly enhanced. Under gamma-ray irradiation, the energy required for gelation is 300% higher than that of ordinary silicone oil, which can meet the usage requirements in extreme environments such as nuclear power and space exploration.

2. The popularization of environmentally friendly production processes has accelerated the green transformation of the industry
With the tightening of environmental protection policies, the phenyl silicone oil industry is actively promoting green production technologies. Domestic enterprises have significantly reduced pollutant emissions during the production process by improving synthesis techniques and adopting new catalysts. For instance, a synthesis technology of amphiphilic phenyl-modified siloxane based on hydrosilylation reaction not only enhances the purity and stability of the product but also achieves low VOCs emissions. Meanwhile, the application of closed-loop production processes has significantly increased the utilization rate of raw materials, reduced production costs, and also minimized the impact on the environment. The relevant plan released by the Ministry of Ecology and Environment clearly lists phenyl silicone oil as a low-volatility alternative. Its vapor pressure at 20℃ is only 0.01Pa, which is much lower than that of traditional solvents such as toluene, in line with the development direction of green manufacturing.

3.The process of domestic substitution is accelerating, breaking the international monopoly pattern
In recent years, the domestic phenyl silicone oil industry has made remarkable progress, with the domestic production rate surging from 32% in 2015 to 68% in 2023. Domestic enterprises have successfully mastered the core technology of high-performance phenyl silicone oil through independent research and development, and the performance of their products is on par with or even surpasses that of international first-line brands. For instance, in the field of electronic packaging, domestic phenyl silicone oil, with its outstanding electrical insulation and thermal stability, has been successfully introduced into many leading domestic enterprises and sold to markets in Asia, Europe and America. In the field of new energy, domestic phenyl silicone oil has performed outstandingly in applications such as photovoltaic module sealing and power insulators, effectively extending the service life of equipment and reducing maintenance costs.

4. Market demand continues to grow and emerging application fields are constantly expanding
With the rapid development of high-end manufacturing, the market demand for phenyl silicone oil has shown a continuous growth trend. In addition to traditional fields such as electronics, chemicals, and textiles, its application in emerging fields like new energy vehicles, smart wearable devices, and medical and health care is also constantly expanding. For instance, in the field of new energy vehicles, phenyl silicone oil is used as a heat transfer medium for battery packs, which can effectively enhance the heat dissipation performance of batteries and reduce the failure rate of equipment. In the medical field, medical-grade phenyl silicone oil has passed biocompatibility tests and can be used for lubrication and coating treatment of medical devices such as artificial heart valves and medical catheters. According to industry reports, the global market size of phenyl silicone oil is expected to exceed 4.5 billion US dollars by 2025, and the Chinese market will become an important growth pole.
