Krytox Performance Lubricants: Corrugator Greases—NSF H-1 Food Grade Registered
Product Information
Krytox™—Setting the Standard for the Corrugating Industry
Since the 1980s, Krytox™ anti-corrosion greases have set the standard for high temperature bearing lubrication in corrugator applications. These products are the same high performance formulation the corrugated industry has trusted for years, and we are pleased to announce, are now registered for incidental food contact.

NSF Registration Means Safety and Confidence
To provide absolute confidence and safety in food-related operations, these products are NSF H-1 food grade registered. Corrugator Krytox™ 226FG and Corrugator Krytox™ 227FG provide you with peace-of-mind and full confidence that Krytox™ greases are non-toxic and completely biologically and environmentally inert.
Krytox™ corrugator greases are recommended for use in high temperature corrugated equipment applications and manufacture of food packaging materials where an H-1 rated lubricant is required.

Reliability and Performance for Your Most Demanding Needs
High temperature, extreme pressure Krytox™ greases excel in the most demanding environments. Their non-oxidizing chemistry and wide temperature range allows them to be used in temperature extremes. Its superior oil film strength reduces friction and abrasive wear to significantly extend equipment life in severe duty applications. Krytox™ provides excellent water washout resistance and superior rust and corrosion protection for bearings and components. Krytox™ is silicone-free, contains no VOC materials or chlorine, and is not hazardous to the atmosphere or ozone layer.

Chemical and Environmental Compatibility
While Krytox™ fluorinated greases are non-reactive, its PFPE chemistry is very different standard hydrocarbon or synthetic chemistries and should never be mixed with non-fluorinated greases.
Krytox™ lubricants are inert and will not react with any materials they may come in contact with. The polymeric nature of these products is extremely resistant to moisture, so it stays in place during cleaning. Cleaners and disinfectants, both acidic and caustic types, do not affect them. Steam and high temperatures will not damage them. They do not damage plastic or elastomer seals or cause corrosion to metals. They are nonflammable and safe for use in oxygen service.
Packing the Bearing
New bearings should be inspected for damage and cleanliness before use. New unlubricated bearings are often coated with hydrocarbon-based rust preventive oils to protect them during storage. These preservative oils must be removed when using Krytox™ as a lubricant. Failure to do so could result in reduced bearing life.
The preservatives coat the bearing surface to prevent rust and corrosion, but, if not removed prior to use, will prevent the grease protecting the metal surface. If on the bearing, the preservative coating can oxidize and harden and create debris that will contaminate the grease.
Storage and Shelf Life
Krytox™ grease and oil lubricants have no expiration date and an indefinite shelf life if unopened and stored in a clean, dry location.
