What is Phenyl Methyl Silicone Oil?
Phenyl Methyl Silicone Oil is a composite silicone oil in which phenyl groups are introduced into the molecular chain of dimethylsiloxane. Compared to methyl silicone oil, it features better high-temperature resistance, radiation resistance, lubricating performance, and solubility, with an operating temperature range of -50℃ to 250℃.
Core Properties and Characteristics of Phenyl Methyl Silicone Oil
Viscosity-Temperature Characteristics and Pour Point
Compared to methyl silicone oil of the same viscosity, phenyl methyl silicone oil has a higher viscosity-temperature coefficient and a lower pour point. This means its viscosity changes more steadily with temperature variations, and it retains fluidity at lower temperatures.
Oxidation and Radiation Resistance
Phenyl methyl silicone oil exhibits excellent oxidation stability and radiation resistance. With increasing phenyl content, its thermal stability significantly improves. Even when heated at 250℃ for thousands of hours in the absence of air, its physical properties remain essentially unchanged. Additionally, it has good radiation resistance, capable of withstanding up to 2×10^8 R of radiation dose at room temperature without failure.
Lubricating Performance
The lubricating performance of phenyl methyl silicone oil surpasses that of methyl silicone oil, making it an effective lubricant under high-temperature conditions. Especially at 200℃, it can continue to operate, demonstrating excellent high-temperature lubrication characteristics.
Organic Compatibility
Compared to methyl silicone oil, phenyl methyl silicone oil has better organic compatibility and can be mixed with vegetable oils, animal oils, and mineral oils, thereby expanding its application range.
