Flame retardant and flame retardant composition using same, molded article thereof, and electric wire with coating

Abstract

The flame retardant of the present invention has a flame retardant (a) component, comprising 50 to 97% by mass of a metal hydrate (a-1) component and 3 to 50% by mass of a filler (a-2) component, wherein the filler (a-2) component contains SiO2, Al2O3 and M2/nO. Here, the total of the metal hydrate (a-1) component and the filler (a-2) component is 100% mass, M represents one or more metal elements selected from a group consisting of K, Na, Mg, Ca, Fe and Zn, and n represents a valence of the metal element. According to the present invention, it is possible to provide a flame retardant capable of providing a molded article and an electric wire with a coating, which are excellent in flame retardancy, abrasion resistance and flexibility, and also have sufficient mechanical strength at low cost.
