LUBRICATING GREASE COMPOSITIONS

摘要

Lubricating grease composition comprising: (i) a base oil; and (ii) a thickener system comprising (i) a lithium soap of a first carboxylic acid selected from C12-C24 hydroxy carboxylic acids and (ii) a lithium soap of a second carboxylic acid selected from C12-C24 branched carboxylic acids, C12-C24 dihydroxy carboxylic acids and mixtures thereof. The lubricating grease compositions according to the present invention have improved oil bleeding and shear stability properties, as well as improved grease lifetime and increased relubrication intervals.
