Abstract
Abstract A water blocking composition for sheathed stranded cables consisting essentially of a gel of (a) a major proportion by weight of a substantially non-volatile petroleum based oil, said oil being an aromatic extract containing aromatic and saturated hydrocarbons and sulfur containing polar compounds in which has been dispersed (b) a minor proportion by weight of a solid gellant which is insoluble in said oil and which does not melt below 100*C., said gellant being selected from the group consisting of a bentonite clay based gellant and a sub-micron particle sized silica gellant, the gel being substantially devoid of any gellant which is soluble in the oil and melts below 100*C.
