Some applications require electrical conductivity. Most greases act as insulators. This special grade of Krytox™ has been formulated with copper powder in grease to act as a conductor of electricity. Krytox oils provide long life and high-temperature stability and lubrication. The addition of copper powder also improves the thermal conductivity of the grease for applications where improved heat transfer is needed; however, it can increase bearing noise and wear. Because GPL 246 is formulated with our Krytox GPL 106 base oil, it retains many of the properties of that oil.
