Abstract
Disclosed are hydrophobic compositions useful for filling the voids within jacketed optical fiber cables. The compositions include about 85 to 95 parts by weight of mineral oil, 5 to 15 parts by weight of a (styrene)-(ethylene/propylene) diblock copolymer having a styrene: (ethylene/propylene) ratio of 37.5:62.5 to 27.5:72.5 and a specific gravity of about 0.90 to 0.95, optional antioxidant, and optional metal deactivator.
