Abstract
This antistatic polyamide composition, comprising at least one polyamide and a sufficient amount of carbon black to make it antistatic, is characterized by the fact that the carbon black is at least a carbon black that is selected from among those having a specific BET surface area, measured according to ASTM Standard D 3037-89, from 5 to 200 m2/g, and DBP absorption, measured according to ASTM Standard D 2414-90, from 50 to 300 ml/100 g.
