<p>This material, essentially characterized in that it is flexible, employs simultaneously the two phenomena of in tumescence and endothermicity to obtain optimal protection characteristics maintaining the element to be protected at a temperature below or in the order of 150 DEG C. when it is subjected to thermal attack corresponding to a flame temperature of 700 DEG to 1000 DEG for a duration of at least one hour for a thickness of the material between 10 and 20 mm, comprises a binder (silicone elastomer) in a proportion of 30 to 35% by weight; a reinforcing charge (a metal oxide compatible with said silicone elastomer) in a proportion of 17 to 23% by weight; an active charge (an intumescent agent) in a production of 38 to 45% by weight; and an insulative charge in a proportion of 5 to 10% by weight, these proportions being relative to the total weight of said material.</p> |
