Product Details:

Krytox Vacuum Pump fluids are used in vacuum pumps and vacuum systems and are used when controlled vapor pressure, nonflammability and nonreactivity are needed. These products can be regenerated back to original properties and reused.

Product Details:

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™ vcuum 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.The long-term anti-rust properties repel moisture, providingextra protection from corrosion of metal parts and bearingsurfaces.

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.

                            Krytox™ XHT-AC and XHT-ACX greases are special hightemperature greases with low oil evaporation that provideanti-wear and rusting protection, and are compatible withall elastomers and plastics. These greases have excellentlubrication over a broad temperature range, but aredesigned to work best at temperatures over 200 °C (400°F). Krytox™ XHT-AC series greases are nonflammable,oxygen-compatible, and chemically inert. Krytox™ greasesprovide extended lubrication intervals and longerequipment life.  

Product Details:

Krytox™ XHT series oils are special extreme high temperature grade oils with low evaporation and extra treatment to allow use at temperatures above the range of normal perfluoropolyether (PFPE) oils. These oils provide excellent lubrication over a broad temperature range. Krytox™ XHT series oils are nonflammable and chemically inert. Krytox™ XHT oils allow extended lubrication intervals and longer equipment life. The oil 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.

Product Details:

Opteon™ SF-79 is a high solvency cleaning agent which is non-flammable and a low environmental impact product for cleaning applications. Typical applications for this product include degreasing, precision cleaning, defluxing, silicone removal, and general solvent cleaning.

Opteon™ Sion represents a safe alternative to chlorinated solvents such as HCFC-225, 141b, TCE and nPB, which are currently being phased out due to health and environmental risks.

The safe exposure limit for nPB has been measured at 5-10 ppm – industry authorities even recommend further reducing to 0.1 ppm – whereas Opteon™ Sion has a safe exposure limit of 201 ppm, which is comparable to everyday rubbing alcohol.

Performance

The cleaning power of Opteon™ SF-79 has been measured up to a 100 KB value, which is a cleaning power standard. Opteon™ Sion can match nPB and other common formulations ounce for ounce, providing all their solvency benefits, while offering a superior toxicity profile.
 

Maintenance

While Opteon™ SF-79 is a safe, effective, and environmentally friendly nPB replacement, nPB requires acid acceptance testing, stabilizer maintenance, and solvent air monitoring for safe and effective use. These additional formulations and processes increase your overall cost of using nPB – making Opteon™ Sion an even better, safer value.
 

Benefits:

• Designed to clean a wide range of soils
• Fast, residue-free drying; offers viscosity to clean oil and grease from small parts, leaving no residue
• Compatible with a broad range of metals, plastics, and elastomers
• Chemically and thermally stable
• Zero ODP and low GWP (< 15 GWP)
• Recyclable and reusable
• Low surface tensions
• Non-flammable
• Allows for the continued use of existing equipment (no or minimal equipment upgrade necessary)
• Easy to handle, easy to store
• Available in multiple package sizes

 

Product Details:

Opteon™ SF80 specialty fluid is designed to meet the high solvency needs in the industrial cleaning market. Opteon™ SF80 is a safe, nonflammable, and environmentally friendly solvent with low global warming potential (GWP) (<2.5) and does not contain any fluorinated greenhouse gases (as listed in Annex 1 of the EU regulations 517/2014), which are all highly desirable in industrial cleaning applications like vapor degreasing. Opteon™ SF80 is a blend of proprietary fluids and trans-1, 2-dichloroethylene (t-DCE) with azeotrope-like properties. Its exceptional solvency power (Kb value = 99) makes it an ideal candidate for replacement of trichloroethylene (TCE), n-propyl bromide (nPB), benzene, perchloroethylene, methylene chloride, and other strong solvency fluids, where maximum cleaning power is a requirement. Opteon™ SF80 is also a great replacement option for solvents with low to medium solvency power, such as HCFC-225, HCFC-141b, HFEs, PFCs, CFCs, and aqueous cleaners.

Product Description

This Krytox grease is a special high temperature grease with low oil evaporation that provides long bearing life and is compatible with all elastomers and plastics. It has excellent lubrication over a broad temperature range but is designed to work best between temperatures 200-300 ⁰C(400-572 ⁰F). It is nonflammable, oxygen compatible and chemically inert.

Product Details:

Product Description

This Krytox grease is designed for use where the temperatures are in the 300 ⁰C (572 ⁰F) 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. The grease is for use in low speed bearings and will shear at high speeds, causing loss of oil. The Oil in the grease can begin to slowly degrade at temparatures above 330 ⁰C (625 ⁰F) and this will occur at an increasing rste as temperatures increase. Relubrication could be required at these temperatures to achieve life.

Product Details:

Krytox™ 227 FG Corrugator grease has an Oil Viscosity of 440 cSt at 40°C and the estimated useful temperature range is -30°C to 288°C.

 

Product Details:

Oxygen Pump Application The NRT series of Krytox™ oils and greases deliver nonreactive, nonflammable, long-lasting performance, even under the demanding temperatures and pressures of reactive gas service. Krytox™ NRT lubricants are compatible with oxygen and other reactive chemicals, and are extremely resistant 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™ lubricants provide 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 last longer. 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
