Abstract

L'invention concerne l'industrie des appareils et machines électriques. Elle a pour objet des compositions polymères conductrices réticulées manifestant un coefficient de température positif. Ces nouvelles compositions sont préférées pour la fabrication de rubans chauffants flexibles et autres accessoires agissant comme régulateurs de l'intensité électrique par l'intermédiaire d'un élément à coefficient de température positif.The invention relates to the electrical machinery and apparatus industry. It relates to crosslinked conductive polymer compositions exhibiting a positive temperature coefficient. These new compositions are preferred for the manufacture of flexible heating ribbons and other accessories which act as regulators of electrical intensity through a positive temperature coefficient element.
