This material, essentially characterised in that it is flexible, employs simultaneously the two phenomena of intumescence and endothermicity to obtain optimal protection characteristics maintaining the element to be protected at a temperature below or in the order of 150°C when it is subjected to thermal attack corresponding to a flame temperature of 700 to 1 000° 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 weigh ; an active charge (an intumescent agent) in a proportion of 38 to 45% by weight; and an in insulative charge in a proportion of 5 to 10% by weight, these proportions being relative to the total weight of said material.
