What is Phenyl Methyl Silicone Oil?

Phenyl methyl silicone oil, also known as phenylmethyl silicone oil, is a linear siloxane polymer with phenyl chains added to the side chain of polydimethylsiloxane. Its polymer chain changes from flexibility to rigidity with the increase in phenyl content. Specialty silicone oils have properties that traditional simethicone oils cannot meet, providing application-specific characteristics, such as high refractive index, ultra-high temperature resistance, and ultra-low temperature resistance.

Phenyl Methyl Silicone Oil molecular structure

The viscosity of phenylmethyl silicone oil usually increases with the increase of the phenyl content of the molecular chain. Due to the high electron cloud density of the phenyl functional groups in the polymer chain, these siloxane polymers are more thermally stable (peaking at 350 °C) and less cold resistant (down to - 100C°), and have stronger UV resistance. The addition of phenyl groups to siloxane polymers improves compatibility with hydrocarbons and imparts ease of compatibility with other silicone polymers.

Why use phenyl methyl silicone oil??

Phenyl methyl silicone oil may be present in everyday products you use in your life. Maybe you pay attention to your cosmetics. Due to their excellent formulation compatibility, phenyl siloxane polymers are used by cosmetic ingredients to improve the properties of cosmetic formulations, such as reducing stickiness, and greasiness, and enhancing gloss. phenylmethyl silicone oil improves the heat resistance temperature and reliability of open or sealed equipment.

The advantages of heat transfer medium heat transfer oil for equipment are as follows:

❐ Higher temperature resistance, more flexible operation.
❐ Reduce traditional equipment investment and daily maintenance costs.
❐ Significantly reduce the operating pressure of the heating system and enhance the safety of the equipment.
❐ The same system meets the requirements of different functions (heating, cooling) and is easy to operate.
❐ Evenly, accurately and efficiently transfer heat for a long time.
