Krytox

From Wikipedia, the free encyclopedia

Krytox fluoroether-based grease (left) is often used in laboratories due to its inertness. For high vacuum applications, silicone grease (right) may be preferred

Krytox is a trademark of a family of high performance synthetic lubricants (oils and greases) used in many things from spaceships to computer chips. It is a chemical polymer belonging to the ether family that was patented by the chemical manufacturing giant DuPont. It is a fluorocarbon, based on polyhexafluoropropylene oxide (somewhat similar to PTFE), thermally stable, nonflammable (even in liquid oxygen), nontoxic, and insoluble in water, acids, bases, and most organic solvents. It has very low vapor pressure and can be used between about -60 and +316 to +399 °C. It is highly resistant to ionizing radiation, making it useful for aerospace and nuclear industry. It can withstand extreme pressure and high mechanical stress.
