1. An antistatic or electrically conductive polymeric composition comprising:
a) an electrically insulating polymeric material;
b) a first carbon black material having a statistical thickness surface area (STSA) measured according to ASTM D6556-17 of below 70 m2/g and an oil absorption number (OAN) measured according to ASTM D2414-18 in the range from 70 to 150 mL/100 g in an amount below its percolation threshold concentration; and
c) a second carbon black material having a statistical thickness surface area (STSA) measured according to ASTM D6556-17 of at least 100 m2/g and an oil absorption number (OAN) measured according to ASTM D2414-18 of at least 150 mL/100 g in an amount below its percolation threshold concentration,
wherein a total amount of the first carbon black material and the second carbon black material renders the polymeric composition antistatic or electrically conductive.
