Krytox, discovered in 1959, the polymer that showed remarkable thermal and oxidative stability. Potential uses envisioned then included lubricant for the MACH 3+ turbine engine, hydraulic oil, rocket gearbox lubricant, and even gyroscope oil.
In 1964, new perfluoropolyether (PFPE)-based grease formulations, developed jointly with the U.S. Navy and Air Force. The result being MIL-G-27617, developed specifically for Krytox. The first commercial sales of Krytox were for nonflammable lubricants for the Apollo space program in 1965.
Prior to 1981, the only commercially available Krytox lubricants were aerospace oil and greases. Since then, a very wide range of industries and applications adopted PFPE-based oils and greases. There are PFPE oils and greases for industrial operations, vacuum pump fluids, incidental food contact, automotive uses, reactive gas, and, of course, military applications—to name just a few.
