GREASE COMPOSITION FOR ELECTRIC CONTACT

摘要

PROBLEM TO BE SOLVED: To provide a grease composition for electric contact that has excellent broad temperature area actuation force properties and shows excellent contact stability even after it is exposed to high-temperature conditions, for example, the lead free-flow soldering process. SOLUTION: The grease composition for electric contact is composed of a thickener including a base oil including synthetic hydrocarbon oil, a lithium complex soap comprising lithium salt of a hydroxy group-bearing higher fatty acid of 12 to 24 carbon atoms and lithium salt of a dibasic acid of 4 to 12 carbon atoms and of a phenolic antioxidant that has an extrapolation weight-decreasing starting temperature of≥220°C according to the differential thermogravimetric analysis.
