Abstract

Graphite and conducting carbon black have been added to magnesium catalyzed cast polyamide-6. Surface resistivity has been measured on samples containing various amounts of additives in wet, standard, and dry states. The samples exhibited antistatic properties at already 2.5 wt% graphite loading. To reach similar properties 1 wt% high conducting graphite and 0.5 wt% high conducting carbon black was needed. It is important to note, that in the case of the high conducting additives above a certain concentration (above 2 wt% for high conducting graphite and above 0.5 wt% for high conducting carbon black) the surface resistivity decreases rapidly to the order of 107 Ω, belonging to the electrostatic dissipative class.
