Krytox LVP

Krytox LVP high-vacuum grease performs over extremes of temperature and pressure that hydrocarbon, silicone, and chlorofluorocarbon greases can’t match. –15–300°C (0–570°F), at vapor pressures as low as 10–13 mmHg, and in even the most chemically severe environments, Krytox® LVP grease gives dependable, proven performance.

Additionally, Krytox high-vacuum grease is non-flammable, insoluble, and chemically inert. It is also an excellent lubricant and sealant. And Krytox LVP grease offers all these features at a price that is less expensive than many hydrocarbons, silicone, and chlorofluorocarbon greases. Krytox LVP high-vacuum grease is used as a sealant or lubricant in vacuum systems. Chemically inert and offering superior lubrication properties, LVP grease combines the extremely low vapor pressure of Krytox fluorinated oil, which is based on the most stable type of perfluoroalkylpolyether available, with a fluorocarbon thickener.

Thus, Krytox LVP grease will not explode, ignite, decompose, react to form gummy or solid deposits or act as fuel for fires. Krytox® grease retains its lubricating ability at temperature extremes ranging –15–300°C (0–570°F) and offers complete oxidation resistance. All these features add up to lower wear and longer life for equipment and components—so important when access for component repair or replacement is difficult or impossible.

Krytox LVP grease is nonflammable under all conditions likely to be encountered in service. It shows no autogenous ignition, flash, or fire points up to the highest temperature tested, 649°C(1200°F), in standard ASTM tests.

At elevated temperatures and pressures, Krytox LVP high-vacuum grease is highly resistant to attack by gaseous and liquid oxygen. As a result, it is the lubricant of choice in industries that manufacture or use oxygen. Tests confirming the non-reactivity of Krytox™ lubricants with oxygen were performed at a variety of conditions.
