Abstract

L'invention concerne une matière première de ferrule MT et un procédé de préparation associé. Ladite matière première de ferrule comprend les composants suivants en pourcentage en masse : 14,5 % à 35 % de sulfure de polyphénylène, et 55 % à 85 % d'une charge inorganique, la charge inorganique étant au moins l'un du dioxyde de zirconium, du dioxyde de silicium, de l'alumine, de l'oxyde de fer, de l'oxyde de zinc et du carbonate de calcium. Concernant les défauts de matières premières de ferrule MT existantes, la matière première de ferrule MT préparée par le procédé de la présente invention présente une meilleure stabilité dimensionnelle et un coefficient de dilatation thermique inférieur, tout en présentant des coûts inférieurs, et une durée de vie plus longue.
