Abstract
Conductive polymer compositions comprise carbon black or graphite dispersed in a polymer and further comprise an arc-controlling additive such as alumina hydrate. Such compositions have improved performance when subjected to electrical stress and are, therefore, particularly useful in circuit protection devices.
