Abstract:
    The production of fire resistant articles is described comprising a normally combustible carrier element having applied thereto sodium silicate which is heat foamable to produce a further element capable of resisting the passage of fire and/or heat therethrough in the event the article is exposed to fire and/or heat. In a typical embodiment the articles comprise corrugated container-wall structures, in which the sodium silicate layer serves as the fire and/or heat barrier, laminating adhesive, and provides structural strength.
