Vacuum grease is a lubricant with low volatility and is used for applications in low pressure environments. Lubricants with higher volatility would evaporate, causing two problems:

• They would not be present to provide lubrication.
• They would make lowering the pressure below their vapor pressure difficult.

In electronics manufacturing processes, vacuum grease is often used to prevent corrosion.
