Krytox Performance Lubricants

Krytox™ GPL 226 grease contains an anti-corrosion/antiwear inhibitor and is ideal for corrosive environments, where there is no danger of the sodium nitrite additive reactingwith chemicals or causing contamination problems. Typical applications are automotive bearings, sealed pump bearings,electric motor bearings, and general-purpose bearings.Krytox™ oils and greases are silicone free. They do not contain any VOC materials or chlorine, and are not hazardous tothe atmosphere or ozone layer. They are biologically and environmentally inert.The fully fluorinated Krytox™ high-temperature stability provides bottom-line savings from improved reliability, and areduction in grease usage and manpower through extended re-lubrication intervals. Excellent film strength reduces wearto reduce maintenance costs. Under high loads, the viscosity increases to provide support and absorb the pressure.

Krytox™ oils and greases are the product of choice in extreme temperature conditions. Most other products cease to perform satisfactorily when conditions become extreme.

Krytox GPL 227 is cost-effective across a wide range of applications. Due to its inert nature, It provides a much longer usable life; and the longer usable life allows it to remain for considerable periods of time before needing to be replaced. Performance anti-corrosion additive is combined to enhance its ability to protect metallic surfaces from corrosion caused by moisture.

Krytox 227 is non-flammable chemically inert. It enables extended lubrication intervals and longer equipment life. Typical applications include corrugator and paper machine bearings, aluminium can manufacturing bearings, vacuum sputtering machines, welding machines, linear bearings, high temperature fans, clean rooms, chlorine service, textile equipment, stenter frames etc..

Krytox™ metallization fluids are a range of colorless, fluorinated fluids designed for use in metallization processes. Based on perfluoropolyether (PFPE) chemistry, they are non-reactive, nonflammable, chemically inert, and stable to oxidation.

Krytox™ metallization fluids have outstanding evaporation properties, allowing metallization processes to run at lower and more constant evaporation temperatures. The distillation process used to make these fluids produces a product that results in less residue upon evaporation.

Krytox™ CBF 100 fluids will have a boiling point of about 318 °C (604 °F). Krytox™ CBF 103 should not be used as a boiling fluid because of the possibility of decomposition at higher temperatures.

Krytox™ 143 series oils are clear, colorless, fluorinated synthetic oils that are non-reactive, nonflammable, safe in chemical and oxygen service, and are long-lasting. Krytox™ is a perfluoropolyether (PFPE)—also called perfluoroalkylether (PFAE) or perfluoropolyalkylether(PFPAE)—with the following chemical structure:F-(CF-CF2-O)n-CF2CF3| where n = 10–60CF3The polymer chain is completely saturated and contains only carbon, oxygen, and fluorine. On a weight basis, a typical Krytox™ oil contains 21.6% carbon, 9.4% oxygen,and 69.0% fluorine. All standard grades of grease are thickened with high efficiency PTFE, whose formula is (CF2-CF2)n. This special high efficiency thickener has a melting point of 325 °C (617 °F), and has low molecular weight and submicron (0.2 μ) particle size for higher performance in bearings.

Krytox 240 series greases are white, buttery greases with all of the same properties as the 143 series oils that they are made from, but they are in grease form. The 240AZ, 240AB and240AC met MIL-PRF-27617 general specifications. Many of the other 240 series products meet other specifications for individual applications.

The NRT series of Krytox™ oils and greases deliver nonreactive, nonflammable, long-lasting performance, even under the demanding temperatures and pressures ofreactive gas service. Krytox™ NRT lubricants are compatible with oxygen and other reactive chemicals, and are extremelyresistant to water washout. Krytox™ NRT lubricants are also compatible with polymers used in seals, O-rings, and valves.The superior film-forming capability of Krytox™ lubricantsprovide a thick oil layer that reduces friction and wear,extending equipment life in severe duty applications. The non-oxidizing nature of the oils makes the greases lastlonger. The oils don’t gum up as they age; so, they won’t harden the greases and cause catastrophic failure.Krytox™ oils and greases are perfluoropolyether (PFPE) lubricants—also called perfluoroalkylether (PFAE)or perfluoropolyalkylether (PFPAE). Many of the NRT series of Krytox™ greases are thickened with a unique polytetrafluoroethylene (PTFE) with the formula (CF2-CF2)n. This special high efficiency thickener has a melting point of 325 °C (617 °F), low molecular weight,and submicron (0.2 μm) particle size.

Some applications require electrical conductivity. Most greases act as insulators. This special grade of Krytox® has been formulated with copper powder in grease to act as a conductor of electricity. Krytox® oils provide long life and high-temperature stability and lubrication. The addition of copper powder also improves the thermal conductivity of the grease for applications where improved heat transfer is needed; however, it can increase bearing noise and wear. Because GPL 246 is formulated with our Krytox® GPL 106 base oil, it retains many of the properties of that oil. Consult our "Krytox® Oils and Greases" brochure, H-58505, for more information.

Low pressures. Extremely high or low temperatures. Hostile environments. Whatever special needs your system might have, Krytox™ low vapor pressure (LVP) high-vacuum grease works—safely, reliably, and cost-effectively.

Krytox™ LVP high-vacuum grease performs over extremes of temperature and pressure that hydrocarbon, silicone, and chlorofluorocarbon greases can’t match. From –15–300 °C, 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™ LVP 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 vacuum-rated hydrocarbon, 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, Krytox™ 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 from –15–300 °C 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™ vacuum pump fluids (VPF) are used in applicationswhere conventional vacuum pump oils cause safety, wastedisposal, and maintenance problems. They are nonflammableand eliminate the chance of fire in pumps. They are nonreactiveand safe to use in oxygen systems. They can replacecompetitive PFPE fluids as well as any other type of vacuumfluid. Krytox™ fluids do not contain acetal groups, which aresusceptible to attack by Lewis acids (see Figure 2 and Table3). This gives Krytox™ superior stability as a vacuum pumpfluid. Krytox™ vacuum fluids are precisely distilled to providelow vapor pressures and superior performance (see Figure 1).In addition, Krytox™ fluids are recyclable.Krytox™ XP VPF oils contain a soluble additive to prevent rust.

This patented additive enhances the performance of Krytox™ VPF fluids, giving them improved performance properties.

Krytox™ NRT 8908 grease is a special high-pressure oxygen paste with excellent lubrication over a broad temperature range. This product has been formulated with special oils and thickeners for use in the highpressure oxygen industry. Krytox™ NRT 8908 received arating of 350 bar at 60 °C (140 °F) in the BAM oxygen reactivity test, making it a great choice for valves in high pressure service.

Krytox™ XHT-BD series oils are special extreme high temperature greases with low oil evaporation that are thickened with a non-melting thickener to allow use at temperatures above the melting point of common greases. They have excellent lubrication over a broad temperature range. Krytox™ XHT-BD series greases are nonflammable and chemically inert. Krytox™ allows extended lubrication intervals and longer equipment life. Krytox™ XHT-BD greases are designed for use where the temperatures are in the 288 °C (500 °F) range and higher, where there is a danger of melting the standard PTFE thickener. This grease uses a special non-melting high temperature thickener. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures. Krytox™ XHT-BD greases are for use in low speed bearings or in pillow housings and will shear at high speeds, causing loss of oil in sealed bearings. The oil in the grease can begin to slowly evaporate at temperatures above 330 °C (626 °F), and this will occur at an increasing rate as temperatures increase. Re-lubrication could be required at these temperatures to achieve optimum life.

Krytox® GPL-407 grease is made using a nonmelting thickener instead of the normal Krytox® PTFE. This change from PTFE to silica boosts the temperature capability of the grease from approximately 316°C (600°F) to an upper limit determined by the evaporation/breakdown temperature of the oil. GPL-407 is made from GPL-107 oil, which, with proper ventilation, can withstand up to 399°C (750°F) and higher temperatures for brief periods. With replenishment/relubrication, it can last longer. While GPL-407 is not meant to replace the GPL- 200 series at temperatures below 288–316°C (550– 600°F), it does extend the range for using fluorinated greases to beyond the 316°C (600°F) limit of PTFE and Teflon® thickened greases.

Krytox™ XHT-S and XHT-SX greases are special high temperature greases with low oil evaporation that provide long bearing life and are compatible with most elastomers and plastics. These greases provide excellent lubrication over a broad temperature range, but are designed to work best at temperatures over 200 °C (400 °F). Krytox™ XHT-S series greases are nonflammable, oxygencompatible, chemically inert, and provide extended lubrication intervals and longer equipment life.

Krytox™ 283 AC is a white anticorrosion aerospace grade grease that contain sodium nitrite. It provides rust protection at ambient temperatures, corrosion protection at high temperatures, and anti-wear protection.
