There are several common types of silicone oil:
1. Methyl silicone oil: The most common type of silicone oil, its high stability and low volatility make it suitable for various industrial applications, including silicone bonding.

2. Phenyl silicone oil: Due to its high heat resistance and oxidation resistance, it is often used in applications that require stable operation at high temperatures, such as electronic devices and aerospace materials.

3. Ethyl silicone oil: Similar to methyl silicone oil, but with higher lubrication performance and better solvent resistance, suitable for some special bonding and packaging processes.

4. Fluorosilicone oil: It has excellent chemical and oil resistance, suitable for applications in extreme environments such as aerospace and automotive industries.
