LVP

Performance LubricantsHigh-Vacuum Grease Performs Dependably—No Matter WhatConditions Your System Operates Under

Product Information
Low pressures. Extremely high or low temperatures.
Hostile environments. Whatever special needs yoursystem might have, Krytox™ low vapor pressure (LVP)
high-vacuum grease works—safely, reliably, and costeffectively.

Krytox™ fluorinated grease was first used as a highly
reliable, low-friction lubricant in aerospace projects, suchas the Lunar Rover’s traction motors. It was in this andother similar critical applications that Krytox™ lubricantsearned a reputation for superior performance.

Krytox™ LVP high-vacuum grease performs over extremesof temperature and pressure that hydrocarbon, silicone,and chloro­fluorocarbon greases can’t match. From–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.

Today, Krytox™ products are proven performers that aresetting the industry standard for safety, reliability, andcost-effectiveness.

Additionally, Krytox LVP high-vacuum grease isnonflammable, insoluble, and chemically inert. It is also anexcellent lubricant and sealant. And Krytox™ LVP greaseoffers all these features at a price that is less expensive
than many vacuum-rated hydrocarbon, silicone, andchlorofluorocarbon greases.

Krytox™ LVP high-vacuum grease is used as a sealantor lubricant in vacuum systems. Chemically inert andoffering superior lubrication properties, Krytox™ LVP
grease combines the extremely low vapor pressureof Krytox™ fluorinated oil, which is based on the moststable type of perfluoroalkyl­polyether available, with afluorocarbon 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 from
–15–300 °C (0–570 °F) and offers complete oxidation
resistance. All these features add up to lower wear andlonger life for equipment and components—so importantwhen access for component repair or replacement isdifficult or impossible.

Krytox™ LVP

Performance LubricantsApplications• Sealant or lubricant in vacuum systems

Krytox™ LVP is not reactive with any of the following
materials when tested at room temperature:• High-temperature bearing, valve, and O-ring lubricant• Ethyl alcohol• Oven conveyor chain and bearing grease• Hydrazine• Pressure relief valve lubricant• Diethylenetriamine• Any use that requires high-temperature stability, lowvapor pressure, or chemical inertness• 90% hydrogen peroxideProperties• JP-4 turbine fuelChemically Inert• Unsymmetrical dimethyl hydrazine

Krytox™ LVP high-vacuum grease has demonstrated an
exceptionally high degree of chemical inertness to manyhighly reactive chemicals. For example, Krytox™ LVP
grease shows no evidence of reactivity when exposed to:• Aniline• Boiling sulfuric acid

• Chlorine or bromine• Fluorine gas at 200 °C (392 °F)

Nonflammable• Chlorine trifluoride at 10–50 °C (50–122 °F)• Molten sodium or potassium hydroxide at 318–360 °C(605–680 °F)

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.

• Hydrogen gas at 250 °C (482 °F) and 250 psi

Compatible with Oxygen• Ammonia gas at 250 °C (482 °F) and 50 psi

At elevated temperatures and pressures, Krytox™ LVP
high-vacuum grease is highly resistant to attack bygaseous and liquid oxygen. As a result, it is the lubricant ofchoice in industries that manufacture or use oxygen.

• Uranium hexafluoride gas at 50 °C (122 °F)• Nitrogen tetroxide• Inhibited red fuming nitric acid
• Halogen acids

Tests confirming the non-reactivity of Krytox™ lubricantswith oxygen were performed at a variety of conditions.
