Product Overview

Krytox™ XHT-500 Oil is a special extreme high temperature grade oil with low evaporation and extra treatment to allow use at temperatures above the range of normal perfluoropolyether (PFPE) oils. Krytox™ XHT-500 Oil provides excellent lubrication over a broad temperature range.   All Krytox™ XHT series oils are nonflammable and chemically inert.

Features & Benefits

Krytox™ XHT-500 Oil allows for extended lubrication intervals and longer equipment life. The oil 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.

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.
