Abstract

The invention relates to conductive polymer compositions comprising carbon black or graphite dispersed in a polymer. The compositions of the invention further comprise an arc-controlling additive such as alumina trihydrate. Such compositions have improved performance when subjected to electrical stress and are, therefore, particularly useful in circuit protection devices.
