Abstract
The invention generally relates to gelled oil compositions which employ aluminum complex soaps as gelling agents. The gelled oils comprise an oil component, a bleed inhibitor of polybutene, and optional amounts of antioxidant and pour point depressant. The gelled oils are particularly suited for use as buffer tube gels and as filling compounds for waveguides.

A gelled oil composition comprising about 40 to 90% of an oil component, about 4 to 15% of an aluminum soap complex, and about 5-50% of a bleed inhibitor comprising the combination of a synthetic oil selected from the group consisting polybutene, polyisoprene, polyhexene, polyheptene, polyoctene and polynonene and at least one styrene-rubber block copolymer.
A buffer tube gel composition comprising about 20-90% of an oil component, about 5-50% of a bleed inhibitor comprising the combination of polybutene and at least one styrene-rubber block copolymer, and about 4-30% of an aluminum soap complex wherein the oil component and the bleed inhibitor are in the weight ratio of about 7:3-1:1.
