  • Flame retardant thermoplastic resin composition
    Patent number: 8202450
    Abstract: A flame-retardant thermoplastic resin composition comprising at least a plant-derived resin (A) and a flame retardant (B), wherein the weight proportions of the individual components in the flame-retardant thermoplastic resin composition are: 30?W1<55.5 44.5<X1?70 wherein W1 is the percentage by mass of the plant-derived resin (A) and X1 is the percentage by mass of the flame retardant (B), and 90% by mass or more of the flame retardant (B) is composed of a metal hydrate containing an alkali metal-based substance in an amount of 0.2% by mass or less.
    Type: Grant
