Thermoplastic composition comprising chemically modified carbon black and their applications

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 m2/g, preferably 35 to 60 m2/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.
