Abstract

L'invention concerne une composition à coefficient de température positif. Il s'agit d'une composition qui comprend : 1. Un polymère réticulé; et 2. Des particules conductrices qui sont noyées dans le réseau réticulé du polymère et qui ont une granulométrie d'au moins 18 millimicrons, caractérisée en ce qu'elle a une fraction de gel d'au moins 0,6 et présente au moins une température Tc utile, que le polymère est dérivé d'une gomme présentant à 25 degrés C une résistance à la traction d'au moins 0,35 kg/cm**2 à 20 % d'allongement et que la composition a une température Tc qui n'est pas inférieure de plus de 45 degrés C à la température Tr . Application à la fabrication de rubans chauffants et autres accessoires agissant comme régulateurs de l'intensité électrique.
