DuPontâ¢ Krytox Â® oils and greases are high-performance perfluorinated lubricants used for a variety of applications. Used where temperatures commonly exceed 250Â°F or fall below 0Â°F.
Krypton is also used in lasers. Krypton-fluorine lasers are insanely powerful: one pulse from these lasers has about 500 times the power of the entire electrical grid of the USA. These pulses only last a very short time though: about four billionths of a second. Blink and youâll miss it.
