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 employed alongside other gases to make luminous â neon light â style signs that glow with a greenish-yellow light. Krypton is used as a filling gas for energy-saving fluorescent lights and as an inert filling gas in incandescent bulbs.rypton is considered to be non-toxic. Characteristics: Krypton is a colorless, odorless, inert gas. Although it is extremely unreactive krypton can react with the very reactive gas fluorine. A few compounds of krypton have been prepared, including krypton (II) fluoride and krypton clathrates.
