摘要： What is disclosed is an improved thermoplastic composition for use in wire and cable manufacturing processes, which features the use of from about 15 to 45 percentage by weight of a modified furnace carbon black having a specific surface area of from about 35 to 250 m.sup.2 /g, preferably 35 to 60 m.sup.2 /g, as measured by the nitrogen adsorption surface area method. The modified carbon black is prepared by combining the carbon black with a specified amount of amine, under certain conditions, and heating the reactive mixture for an extended period.
