The reason why phenylmethyl silicone oil can become the preferred choice of high-temperature lubricant is that it has many excellent properties. First of all, the phenyl group introduced into its molecular chain gives it excellent high-temperature resistance, which can maintain lubrication effect in high-temperature environment and is suitable for high-temperature equipment such as engines and steam turbines. Secondly, phenylmethyl silicone oil has excellent antioxidant properties, which can resist oxidation and maintain stable performance during long-term use. In addition, it also has excellent lubricating properties, which can effectively reduce friction and wear and extend the life of equipment. At the same time, phenylmethyl silicone oil has high chemical stability and can maintain its performance unchanged in harsh environments, such as high temperature, high pressure, strong acid and alkali. In addition, it also has electrical insulation, ozone resistance, corona resistance, hydrophobicity and moisture resistance, and is widely used in medical equipment, electronic appliances and other fields. In summary, phenylmethyl silicone oil has become an ideal material for high-temperature lubrication due to its high-temperature resistance, oxidation resistance, lubrication and chemical stability.
