Widely used in vacuum systems to ensure efficient operation by providing lubrication and sealing. It helps in maintaining low pressure by reducing friction and wear in rotary vane and piston pumps. Commonly applied in industries such as pharmaceuticals, electronics, and food processing for creating and maintaining vacuum conditions. Its thermal stability and low vapor pressure make it suitable for high-temperature environments. Also used in laboratories for equipment like vacuum ovens and freeze dryers. Ensures smooth functioning and longevity of vacuum pumps by preventing corrosion and contamination.
