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!
