FIELD: lubricants.
SUBSTANCE: invention proposes a lubricant comprising the following components, wt.-%: perfluoropolyester based on product of the oligomerization reaction of hexafluoropropylene oxide, 93.5-96, and hydrophobized silica gel, 4-6.5. Proposed lubricant can be used in friction units working in broad range of environment temperatures. Invention provides expanding the temperature working range (from -45°C to +150°C), enhancing stability to components of rocket fuel and gaseous oxygen.
EFFECT: improved properties of lubricant.
