Description

ABSTRACT:
Conductive plastic parts having defined electrical properties within a relatively narrow range are produced by controlling the dosage relationship between a given plastic and a conductive material, such as long-chain conductive lampblack, as a function of an electrical value (i.e., surface resistance) measured at an extruded admixture of the plastic and conductive materials, rather than by a gravimetrical or volumetrical relation.
