Due to its excellent performance, phenyl silicone oil can be applied to many fields of national life and production. In the application field of methyl silicone oil, methyl phenyl silicone oil can be used to exert its characteristics of low temperature resistance, high temperature resistance, lubricity, and compatibility. Low phenyl silicone fluids are particularly suitable for applications requiring a high degree of cold resistance; Medium phenyl and high phenyl silicone oil has high thermal stability, as well as good radiation resistance, can be used as heat treatment bath for metal products, high temperature heating oil, gas chromatography carrier, high and low temperature lubricating oil of electronic and electrical equipment, high temperature grease made of carbon black, lithium soap or molybdenum disulfide can be used for high temperature fan bearings, ball bearings, automobile engines, textile dryers, etc.; In addition, it also has a wide range of applications in hydraulics, instrumentation, electrical insulation and other aspects. Phenyl vinyl silicone oil and phenyl hydrogen-containing silicone oil can be used to prepare high temperature resistant irradiation resistant plus molding silicone rubber.
