| When you're choosing a lubricant for critical applications, there's no room for doubt. Maximum durability isn't just desired, it's required. That's when you need the most advanced lubricant formulated from space-age fluoropolymer technology.
DuPont™, the worldwide leader and innovator of performance lubricants, welcomes you to explore our diverse portfolio of oils and greases.
The Krytox® Product Line Delivers Performance. When compared to other lubricants, only Krytox® oils and greases combine stability, high-temperature performance, nonflammability, and chemical inertness with outstanding lubrication under a variety of conditions.
Environmental Safety. Using Dupont™ Krytox® oils and greases reduces or eliminates the need of hydrocarbon lubricants and their potential environmental impact. They last significantly longer, so less lubricant is needed. They are nontoxic and do not release volatile organic compounds into the atmosphere.
Cost-Effectiveness. Krytox® lubricants are cost-effective across a broad range of applications because of their superior protection and useful life relative to traditional hydrocarbons, silicones and other lubricants. This allows equipment manufacturers to extend warranties and manufacturing plants to reduce costly downtime and maintenance due to component failure. Our GPL oils and greases are prices very competively versus fluorosilicones and CTFE products.
General Properties. With 200 years of trusted DuPont™experience, Krytox® performance lubricants are the products of choice for applications where complete nonflammability, oxygen compatibility, and resistance to aggressive chemicals are requirements. Krytox® oils and greases offer a unique combination of properties that provide exceptional, yet cost-effective solutions to your most difficult lubrication problems. Krytox® provides superior protection and load-carrying ability under the most severe conditions.
Nonflammability. All Krytox® oils and greases are completely nonflammable. They contain only carbon, oxygen, and fluorine. They will not burn or support combustion, even in 100% liquid or gaseous oxygen.
Chemical Inertness. All Krytox® oils and greases are chemically inert to virtually all chemicals used in manufacturing operations, including oxygen, chlorine, sulfuric acid, and nitric acid, to name a few. They are insoluble in most solvents except high fluorinated ones. They are resist to water and stream.
Compatibility with Elastomers and Plastics. Krytox®is compatible with all elastomeric seal materials and engineering plastics. The limiting factor would be the thermal stability of the material you are lubricating.
Compatibility with Metals. Due to their low surface tension, krytox will easily wet metallic surfaces. Because they are chemically inert, they have no effect on metals up to 288°C (550°F). Many metals can be used above this temperature (call for a detailed listing). |
A Wide Range of Applications.Kytox®was developed to provide the best protection for bearings, valves, and other components in high-temperature service, up to 343°C (650°F). They are cost-effective across a wide range of applications because of their long life. A few of the many current uses include:
Industrial. All bearings, valves and seals, corrugator and paper machine bearings, aluminum can manufacturing bearings, vacuum sputtering machines, welding machines, gear oil, linear bearing lubricant, high temperature fans, clean rooms, chlorine service, acid service, textile equipment, tenter frames, high speed motors, instrument bearings, sealed for life motors, conveyor system in glass and aluminum plants, textile calendar roll bearings, brick kiln car bearings, and film blowing machines, lubricant for valve stem packing, relief valve lubricant, O-ring lubricant, steam turbine control valves, and low emissions valve stem packing lubricant.
Corrugator Industry. High-Temperature Anticorrosion greases are the standard lubricant for grease lubricated high temperature bearings in corrugator service. They provide protection ferom rusting, high temperature corrosion, and wear while maintaining excellent lubricity over a broad temperature range. Corrugator Krytox 226 FG and Krytox 227 FG are nonflammable, chemically inert, and provide for significantly easier cleanup at roll change versus most other lubricants. Krytox allows extended lubrication intervals and longer equipment life. Although normally provided in an NLGI Grade #2, other grades are available upon request. Typical applications include preconditioner rolls, single facers and double backers.
Aviation. Fuel resistant grease, oxygen compatible grease, ventilation fan bearing grease, cruise missle rear main bearing lubricant, starter bearing grease, emergency generator bearing grease, missile launch platform gear lubricant, space shuttle lubricant, and sealant.
Pumps. Vacuum pump fluid for corossive and hazardous service, bearing grease for chemical pumps, O-ring lubricant, and barrier fluid between double mechanical seals.
Nuclear. Submerged sump pump bearings, containment cooling fans, snubbers, and control rod drive mechanism fan motors.
Miscellaneous. Anti-seize lubricant, bolt thread lubricant, water purifier lubricant, self-contained breating apparatus lubricant, cryogenic lubricant, vacuum system sealant, drive chains, hydraulic fluids, instrument barrier fluids, heat transfer fluids, geothermal system grease, mold release agent, fishing reel grease, industrial toast making oven conveyor bearings, windmill gearboxes, glove curling conveyor, and most moving or sliding surface.
Thermal and Oxidative Stabiity. The initial decomposition point of Krytox® is 335°C (671°F), far above standard lubricants. More importantly, gaseous decomposition products are given off and no sludge or gummy deposits are formed. In most applications, Krytox® has proven serviceable at continuous temperatures of 288°C (550°F) and intermittent temperatures of 427°C (800°F). |
