Krytox™ XHT-BD Grease

Krytox™ XHT-BD Grease | For Extreme High Temperature

Non-melting thickener with Extra Bonding to substrate

Krytox XHT-BD grease is designed for extreme high temperature with low oil evaporation that are thickened with a non-melting thickener to allow use at temperatures above the melting point of common greases. They have excellent lubrication over a broad temperature range. Krytox XHT-BD grease is nonflammable and chemically inert. Krytox allows extended lubrication intervals and longer equipment life.

Krytox XHT-BD grease is designed for use where the temperatures are in the 288 °C (500 °F) range and higher, where there is a danger of melting the standard PTFE thickener. This grease uses a special non-melting high temperature thickener. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures. Krytox XHT-BD greases are for use in low speed bearings or in pillow housings and will shear at high speeds, causing loss of oil in sealed bearings. The oil in the grease can begin to slowly evaporate at temperatures above 330 °C (626 °F), and this will occur at an increasing rate as temperatures increase. Re-lubrication could be required at these temperatures to achieve optimum life.

Krytox XHT-BD Grease compatibility with metals

Due to their low surface tensions, Krytox oils easily wet metallic surfaces; and, because of their inertness, Krytox oils have little or no adverse effect on metals. Testing of metals at 340 °C (644 °F) in the absence of air has shown little evidence of corrosion. In the presence of air, corrosion was slightly higher. The presence of molybdenum in the metals improved corrosion resistance. Because of its thermal stability and non-oxidizing characteristics, Krytox is a natural high-temperature lubricant. Krytox XHT greases are available with useful temperature ranges up to 360 °C (680 °F) for continuous use, with spikes to 400 °C (752 °F), when used in proper metallurgy with periodic re-lubrication.
