Fire-retarding resin composition and fire retardant composition

Abstract

A fire-retarding resin composition composed of (a) a thermoplastic resin, (b) about 20 to about 60% by weight, based on the total weight of (a), (b) and (c), of a magnesium hydroxide powder whose surface is treated with an alkali metal oleate, and (c) about 0.1 to about 10% by weight, based on the total weight of (a), (b) and (c), of at least one fatty acid metal salt selected from the group consisting of magnesium oleate and aluminum oleate; and a fire retardant composition for thermoplastic resins, said composition comprising (b) a magnesium hydroxide powder whose surface is treated with an alkali metal oleate, and (c) at least one fatty acid metal salt selected from the group consisting of magnesium oleate and aluminum oleate, the weight ratio of (b) to (c) being from 2 to 600:1.
