  • Application Of Phenyl Methyl Silicone Oil

    • As a lubricant, it is used in bearing and instrument lubricating oil;

    • As heat transfer oil, it is used as heat transfer oil in transformers, capacitors and various electronic equipment;

    • As an oil-out medium, it is used in self-penetrating silicone rubber.

  • Advantages Of Phenyl Methyl Silicone Oil

    • High refractive index

    • Excellent thermal stability

    • Excellent compression performance

    • Excellent heat transfer performance

    • High flash point

    • Wide operating temperature range, the usable temperature range of open system is -40~230℃, and the usable temperature range of a closed system is -40~315℃

  • Phenyl Methyl Silicone Oil Boiling Point

    The high boiling point of phenyl methyl silicone oil offers several advantages due to its boiling point, which is typically higher than that of other silicone fluids. Some of these advantages include: 

    High boiling point:the most desirable characteristic  of phenyl methyl Silicone oil, making it a a versatile and reliable material for various industrial and commercial applications. 

    Boiling point range: 200°C to 230°C, making phenyl methyl silicone oils suitable for a wide range of applications where high temperatures are involved, such as in the production of thermal greases and heat transfer fluids. 


    High temperatures resistance: withstand high temperatures without breaking down or degrading, ensuring consistent performance over time. Besides, Phenyl polydimethylsiloxane and phenyl silicone resin can modify phenyl methyl silicone oil's  properties and enhance its thermal stability and chemical resistance.
