  • Resinous construction material having fire-resistant intumescent cap layer
    Patent number: 5458966
    Abstract: Thermoplastic resin sheets, particularly in the form of fiber-reinforced composites, have adherent cap layers, at least one of which comprises an intumescent polydiorganosiloxane-containing barrier material which forms upon ignition a thermally stable foamed char layer. Such articles have improved fire resistance in comparison with similar articles having no cap layer or non-intumescent cap layers.
