This invention relates to a self extinguishing composite laminate which combines flexibility and light weight with high tensile-and tear strength and a high degree of flame resistance. This result has been attained by combination of previously known fire resistance agents so that the different components of the laminate each carries a set of flame resistance composition, designed not only to give the component in itself a high flame resistance, but also with regard to maximizing the synergistic effect with adjacent layers as well as between different chemical compounds. A range and system of composite design has been found, which in a surprising manner makes possible the construction of flexible foldable light weight laminates combining substantially retained strength properties, with a degree of flame resistance not previously attained particularly with olefinic materials without major sacrifice of structural properties. |
