Electrically conductive thermoplastic compositions

Thermoplastic compositions containing reinforcing agents or fillers and carbon black, and made by a specific procedure are described. In certain instances when the reinforcing agents or fillers are more restricted, and other ingredients are present, electrically conductive compositions with very smooth surfaces, and suitable for auto panels and other uses wherein the part may be painted, are described. Also described are the processes of making such compositions, especially when a conductive filler is carbon black. Such compositions are useful for items such as appliance parts, automotive body panels, power tool housings, and electrical and electronic housings.
