DuPontâ„¢ Krytox ™ PFPE/PTFE Greases Have Become the Corrugator Industry Standard

krytox_graisse_cartonnerie.bmpDuPont™ Krytox®lubricants have become the corrugator industry standard for lubricating bearings on heated rolls in single facers and associated equipment. They contribute to eliminating premature defects of rolls caused by inadequate lubrication. Single-facer rolls lubricated with Krytox ™ grease are much easier and faster to replace.

Several factors make Krytox® superior to competing products. Thanks to its chemical structure, it stands up to high temperatures, hostile chemicals and volatile atmospheres. It will not burn. It does not react with oxygen. When it does begin to break down, the byproducts vaporize, leaving no gummy tars or deposits. Krytox®grease, which forms its own sealaround bearings, also resists common solvents and long-term contact with steam and boiling water. Another physical property which contributes to Krytox®‘s superiority as a severe-service lubricant is its density. About twice as dense as the typical hydrocarbon lubricant, Krytox® provides superior load-carrying capability and film-forming characteristics, critical factors in extending the operating life of a bearing.

BHS Guidelines
In accordance with the guidelines in place at BHS, bearings are lubricated with Krytox ™once every four weeks, or the equivalent of 500 hours of operation. Krytox ™ greases have a white, creamy consistency. These unique properties are due to thefact that they contain PTFE as a thickener. Unlike other thickeners used in synthetic greases, such as lithium, PTFE does not break down under heat, allowing Krytox®to stay white. Any discoloration of old grease during relubrication is therefore, in all likelihood, due to wear of the bearings themselves. In other terms, the color of the old grease can serve as an indicator of bearing condition and help to prevent premature failure.

Testimonial by SAICA Pack
Since adopting Krytox® , SAICA Pack has not reported any premature bearing failure. The DuPont grease has since become the lubricant of choice for the facers at all of SAICA Pack’s plants in the U.K.
