PURPOSE:The titled composition which does not evolve any corrosive gases and is excellent in flame retardancy, moldability and strength, obtained by mixing a polyolefin resin with at least one member selected from aluminum hydroxide, etc., and a lanthanide element compound. CONSTITUTION:The purpose flame-retarding polyolefin resin composition is formed by mixing 100pts.wt. (A) polyolefin resin (e.g., polyethylene or ethylene/ vinyl acetate copolymer) with at least 50pts.wt. (B) at least one member selected from the group consisting of aluminum hydroxide, magnesium hydroxide, hydrotalcite and a mixture thereof, and at least 10pts.wt. (C) lanthanide element compound. Examples of component (C) include lanthanum hydroxide, cerium carbonate and terbium oxide. The obtained resin composition can exhibit sufficient flame retardancy even when it is used in a smaller amount, because of a synergistic action of a combination of components B and C. |
