<P>PROBLEM TO BE SOLVED: To provide a non-halogen flame-retardant composition and an electric wire having heat resistance and withstand voltage characteristics in good balance. <P>SOLUTION: The non-halogen flame-retardant composition is obtained by mixing an olefin-based polymer with 30-230 parts by weight of a hydroxide of a metal element of the group 2 or 3, 2-50 parts by weight of an oxide of a metal element of the group 2 or 3 and 2-50 parts by weight of an inorganic substance having ion exchange function based on 100 parts by weight of the olefin-based polymer. The flame-retardant composition has ≤50 J/g heat of crystal fusion of the flame-retardant composition. The electric wire is equipped with a coating composed of the flame-retardant composition and the flame-retardant composition is crosslinked. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
