PURPOSE:To obtain the title composition having excellent mechanical stability at high temperature, low thermosetting tendency and extremely excellent acoustic characteristics, by compounding a mineral oil or synthetic oil with a specific amount of a thickening agent produced by mixing two specific kinds of diurea compounds at a specific ratio. CONSTITUTION:The objective composition can be produced by compounding a mineral oil or a synthetic oil with 2-30wt.% of a thickner consisting of a mixture of (A) 95-10mol% of a diurea compound of formula I (R1 and R3 are saturated 8C alkyl; R2 is diphenylmethane residue) and (B) 5-90mol% of a diurea compound of formula II (R4 and R6 are alkyl-substituted aromatic group or halogen-substituted aromatic group; R5 is tolylene or bitolylene). |
