PURPOSE: To obtain the subject composition capable of realizing excellent plasticity processability and plasticity processing time shortening and improving the surface characteristics of e.g. thin-wall products thus useful for e.g. the photosensitive drums of copiers, comprising each specific base oil, P compound, S compound or fatty acid (ester) at specified proportions. CONSTITUTION: This composition comprises (A) 40-99.8wt.% of a base oil, mineral oil such as machine oil, turbine oil or cylinder oil, or synthetic oil such as polybutene or poly-α-olefin, (B) 0.1-30wt.% of a phosphorus compound such as triphenyl phosphite or tristearyl phosphite, and (C) 0.1-30wt.% of a sulfur compound such as diisobutyl sulfite, a reaction product of oil-and-fat and sulfur or compound of the formula (R<12> and R<13> are each a divalent hydrocarbon group; (x)>=1; (n) is 0 or 1) or a fatty acid (ester) such as oleic acid (methyl ester) or tallow fatty acid (isobutyl ester). |
