Abstract:
Disclosed is an electroconductive grease comprising a fluorine oil, an electroconductive material, and a thickening agent, the electroconductive grease containing 5 to 20 wt. % of carbon black having a DBP oil absorption amount of 250 ml/100 g or less as the electroconductive material, and 2 to 15 wt. % of fluorine-containing resin particles having an average primary particle size of 1.0 μm or less as the thickening agent. The electroconductive grease comprises carbon black having specific properties, and fluorine-containing resin particles, preferably PTFE particles, having an average primary particle size of 1.0 μm or less, and therefore exhibits excellent oil separation characteristics, namely, a remarkably lower degree of oil separation, which can also be reduced to 10 wt. % or less.
