Title (EN) FLAME RETARDANT THERMOPLASTIC COMPOSITIONS
(FR) COMPOSITIONS THERMOPLASTIQUES IGNIFUGES
Abstract:
(EN) Flame retardant compositions that are thermoplastic at extrusion temperatures (240-270 °C) and cross-linked below 210 °C, the cross-linking being reversible at certain temperatures, are disclosed. Said compositions include a polymer (A) having anhydride or hydroxyl functions and a bifunctional reagent (B) having either hydroxyl or anhydride functions, respectively, or (i) a function reacting reversibly with (A) and (ii) a function reacting irreversibly with (A). Said compositions are useful for sheathing electrical cables.
(FR) La présente invention concerne des compositions ignifuges thermoplastiques aux températures d'extrusion (240 à 270 °C) réticulées en-dessous de 210 °C, cette réticulation étant réversible sous l'effet de la température. Elles comprennent un polymère (A) ayant des fonctions anhydrides ou hydroxyles et un réactif difonctionnel (B) ayant soit des fonctions respectivement hydroxyles ou anhydrides soit (i) une fonction réagissant réversiblement avec (A) et (ii) une fonction réagissant irréversiblement avec (A). Ces compositions sont utiles pour revêtir des câbles électriques.
