Extreme Heat Needs Extreme Performance
Extreme applications require a lubricant technology that can stand up to the environment. Krytox™ XHT Oils and Greases are the most thermally stable lubricants from Chemours and provide an ideal solution for heavy-duty, high temperature equipment. Learn how these PFPE technologies deliver next level performance in the most difficult environments below.


Why Use Krytox™ XHT Performance Greases & Oils?
Krytox™ XHT Lubricants provide Superior Thermal Stability compared to both mineral oil and synthetic based lubricants in the market. Krytox™ will maintain chemical integrity and performance in environments up to 750°F.
Krytox™ XHT Lubricants also provide a Completely Inert Chemistry that allows for extended use without concern of contamination or by-product formation in harsh environments.
Krytox™ XHT Lubricants are also Completely Non-Flammable which improves the operational safety of extreme applications for both equipment and personnel.


Conventional Lubricants Cannot Stand the Heat
At elevated temperatures traditional mineral oil-based lubricants will begin to degrade at temperatures above 93°C. Most synthetic lubricants can withstand a slightly higher temperatures in comparison, but are still subject to failure at temperatures over 150°C.
Avoid the sticky, tar-like build-up of inferior lubricant technologies and trust the extreme thermal stability that the Krytox™ XHT portfolio delivers at temperatures up to 400°C!
