Aspects of the disclosure relate to a composition including: from about 35 wt % to about 70 wt % of at least one polyethylene polymer; from about 25 wt % to about 55 wt % of at least one graphite filler; and from about 2 wt % to about 15 wt % of a carbon powder filler having a BET surface area of at least 50 square meters per gram (m2/g). The polyethylene polymer has a density of at least 0.94 gram per cubic centimeter (g/cm3), a melt flow rate (MFR) of at least 10 g per 10 minutes (g/10 min) measured at 190° C. and 21.6 kilogram (kg), and an Environmental Stress-Cracking Resistance (ESCR) of at least 500 hours. The composition has a volume electrical resistivity of less than 5 ohm·centimeter (ohm·cm) and a MFR of at least 4 g/10 min measured at 280° C. and 21.6 kg.
