Used primarily in vacuum pumps to ensure efficient operation by lubricating moving parts and sealing gaps to maintain a high vacuum level. It helps in reducing friction and wear, extending the life of the pump. Suitable for various applications, including laboratory environments, industrial processes, and HVAC systems. Its thermal stability and low vapor pressure make it ideal for use in high-temperature and low-pressure conditions. Also employed in the semiconductor industry for maintaining clean and contaminant-free vacuum environments.
