Title (EN) FIRE-RESISTANT CABLE
(FR) CÂBLE RÉSISTANT AU FEU
Abstract:
(EN) The invention relates to a fire-resistant cable comprising an electrically insulating fire-resistant layer comprising an organic polymer matrix in which a flame-retardant filler comprising a macromolecular network of silicon oxide functionalized by phosphonate functions is dispersed, the electrically insulating layer being obtained from a composition comprising at least one organic thermoplastic polymer and at least one precursor of said flame-retardant filler comprising silicon and phosphorus; and also to a process for preparing said cable.
(FR) L'invention concerne un câble résistant au feu comprenant une couche électriquement isolante résistante au feu comprenant une matrice polymère organique dans laquelle est dispersée une charge ignifugeante comprenant un réseau macromoléculaire d'oxyde de silicium fonctionnalisé par des fonctions phosphonate, la couche électriquement isolante étant obtenue à partir d'une composition comprenant au moins un polymère organique thermoplastique et au moins un précurseur de ladite charge ignifugeante comprenant du silicium et du phosphore; ainsi qu'un procédé de préparation dudit câble.
