Abstract

"COMPOSIçãO DE RESINA DE POLIAMIDA PARA ELEMENTO FUSìVEL, E ELEMENTO FUSìVEL". A presente invenção refere-se a composição de resina de poliamida para elemento fusível, compreendendo 95-5% em massa de copolímero de poliamida (A) e 5-95% em massa de homopolímero de poliamida (B). A composição de resina de poliamida supramencionada para elemento fusível, onde uma camada de silicato de silicato lamelar intumescível (C) está dispersa em nível de ordem molecular e o teor da camada de silicato (C) é 0,1-20% em massa. Elemento fusível que tem uma carcaça e um par de terminais que se projetam para fora da superfície plana especificada da carcaça, e colocados paralelamente entre si, e acomodando um elemento fusível que conecta as extremidades da base dos ditos dois terminais na dita carcaça, onde a carcaça é fabricada a partir da dita composição de resina de poliamida.
