  • Publication number: 20060008664
    Abstract: A flame-retardant fastening product (a molded article and a fabric product) which is made of a flame retardancy-imparting material or contains or/and is coated with the flame retardancy-imparting material, wherein the flame retardancy-imparting material comprises 100 parts by weight of a synthetic resin and 1 to 400 parts by weight of a flame-retardant containing an inorganic flame-retardant which exhibits such a volume change as expansion and/or foaming at the time of combustion, more preferably at least one member selected from the group consisting of hydrated metallic compounds and thermally expansible graphite, the flame-retardant being dispersed in the synthetic resin. Such flame-retardant products are useful as various molded articles and fabric products, such as surface fasteners, slide fasteners, and resin buttons.
