Chemours Krytox™ GPL 246 PFPE Electrical Conducting Grease
Categories:	Fluid; Lubricant; Perfluoropolyether (PFPE)
Material Notes:	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. Thermal conductivity of non-additive Krytox™ GPL 206 grease at 40 °C (104 °F) is 0.127 watts/mK. The Krytox™ GPL 246 grease at 40 °C (104 °F) has conductivity of 0.272 watts/mK. Because Krytox™ GPL 246 is formulated with Krytox™ GPL 106 base oil, it retains many of the properties of that oil. Information provided by Chemours Krytox
