FLAME RETARDANT, FLAME-RETARDANT COMPOSITION USING THE SAME, MOLDED ARTICLE OF THE COMPOSITION, AND COATED ELECTRIC WIRE

摘要

Disclosed is a flame retardant containing a flame retardant component (a) composed of 50-97% by mass of a metal hydrate component (a-1) and 3-50% by mass of a filler component (a-2), wherein the filler component (a-2) contains SiO₂, Al₂O₃ and M_2/nO. In this connection, the total of the metal hydrate component (a-1) and the filler component (a-2) is 100% by mass; M represents one or more metal elements selected from K, Na, Mg, Ca, Fe and Zn; and n represents the atomic valence of the metal element. This flame retardant is excellent in flame retardancy, wear resistance and flexibility, and enables to obtain a molded article having a sufficient mechanical strength and a coated electric wire at low cost.
