Phenyl silicone oil: the "king of performance" in high-temperature environments
Phenyl silicone oil significantly enhances high temperature resistance and radiation resistance by introducing phenyl groups into methyl silicone oil molecules, making it the preferred material for extreme working conditions.


Product features:
The benzene content directly affects the performance: when the benzene content is 7.5%, the brittleness point is as low as -100 ℃, and the low temperature resistance is excellent; When the benzene content is increased to 50%, the temperature resistance reaches 300 ℃ and the radiation resistance is enhanced. Its refractive index is as high as 1.54, which can be used for optical components; The surface tension is as low as 18mN/m, and its lubricity surpasses that of methyl silicone oil. In addition, phenyl silicone oil has self extinguishing properties and does not spread when exposed to fire.


Application areas:


Power industry: In high-voltage transformers, phenyl silicone oil is used as an insulation medium to withstand arc and corona discharge, extending equipment life; Silicone oil used in nuclear power plants must pass radiation resistance tests, and phenyl silicone oil is the only qualified option.
LED packaging: Phenyl silicone oil fills the gap between the LED chip and the housing, ensuring stable light efficiency due to its high transparency and resistance to yellowing; As a heat dissipation medium, its thermal conductivity reaches 0.8W/(m · K), improving heat dissipation efficiency.
In the aerospace field, the sealing ring coating of rocket engines is made of phenyl silicone oil, which can resist thermal shock from -180 ℃ to 3000 ℃; Silicone oil lubricant for satellite solar panels, resistant to cosmic ray radiation.
Chemical equipment: In the sealing of the stirring shaft of the reaction kettle, phenyl silicone oil is resistant to organic solvent corrosion and maintains long-term sealing performance; In the anti-corrosion coating of high-temperature pipelines, it has strong adhesion and prevents medium leakage.
