Regarding the shelf life and stability of phenyl silicone oil, the following is a detailed summary:

1. Shelf life
The shelf life of phenyl silicone oil is usually 3 years. This information has been confirmed by multiple sources, including Baidu Encyclopedia and the official website of Dongguan Airui Chemical Co., Ltd. During the shelf life, phenyl silicone oil should be kept in the original packaging and stored in a cool, dry and well-ventilated place to ensure its stable performance.

2. Stability
Thermal stability:
Phenyl silicone oil has good thermal stability. For example, in hot air at 250°C, its gelation time can reach 1750 hours. This means that in a high temperature environment, phenyl silicone oil can maintain its stable performance for a long time and is not easy to deteriorate or decompose.
Irradiation resistance:
Phenyl silicone oil also has good radiation resistance. This means that when exposed to radiation, its performance is not easily damaged and can maintain stability for a long time.
Other stability:
In addition to thermal stability and radiation resistance, phenyl silicone oil also has high oxidation stability, heat resistance, flame resistance, UV resistance and chemical resistance. These characteristics make phenyl silicone oil maintain its performance stability in a variety of environments and suitable for a variety of applications.

3. Influencing factors
Although phenyl silicone oil has good stability, its performance may still be affected by the following factors:
Storage conditions:
As mentioned above, phenyl silicone oil should be stored in a cool, dry and well-ventilated place. Improper storage conditions, such as excessive temperature or humidity, may cause its performance to deteriorate.
Packaging materials:
The packaging materials of phenyl silicone oil may also have an impact on its stability. Therefore, when selecting packaging materials, ensure that they will not chemically react with phenyl silicone oil or negatively affect its performance.
Usage:
During use, if phenyl silicone oil is contaminated or mixed with other incompatible substances, it may also cause its performance to deteriorate. Therefore, the purity of phenyl silicone oil should be ensured before use, and avoid contact with other incompatible substances.

In summary, phenyl silicone oil has a long shelf life and good stability. However, in order to ensure its stable performance, it is necessary to pay attention to factors such as storage conditions, packaging materials, and usage. Under the premise of proper storage and use, phenyl silicone oil can maintain its stable performance in a variety of environments and provide reliable solutions for various application fields.
