Overview
Krytox™ XHT-BD Grease is a specially engineered high-performance lubricant for environments that experience extremely high temperatures. Krytox™ XHT-BD Grease uses a special nonmelting, high-temperature thickener with a very low evaporating base oil. This combination gives this Krytox™ grease the capacity to be used in applications under higher temperatures where common greases cannot be used due to their low melting points.
Krytox™ XHT-BD is nonflammable, oxygen safe, and chemically inert. It is designed for use in temperatures of 288°C (500°F) and higher, where there is a danger of melting standard PTFE thickeners. Since this grease is formulated using a special nonmelting, high-temperature thickener, Krytox™ XHT-BD also provides extreme-pressure properties and works as a solid lubricant, even when the base oil is depleted.

Features & Benefits
Excellent lubrication over a broad temperature range (−20°C to 300°C)
Great wetting-out performance with low surface tension
Chemically inert
Nonflammable
Extended lubrication intervals and equipment life
Excellent compatibility with elastomer O-rings
Slightly tacky and will stay in place
Problems Solved
Loss of oil in grease system due to extremely high temps
Melting grease thickener technology
Corrosion, rust, or metal surface damage in very hot environments
Poor sealant performance
Applications
Krytox™ XHT-BD Grease can be used in low-speed bearings and pillow housings with shear at high speeds that traditionally causes loss of oil in sealed bearings. It is a superior grease that can be used successfully across a wide range of applications exposed to extreme temperatures like aviation, textile, metal processing, and industrial manufacturing.
The base oil in Chemours Krytox™ XHT-BD can begin to slowly evaporate at temperatures above 330°C (626°F), and this rate will increase exponentially as temperatures increase.
