A fire and high temperature protection product is provided which comprises an air laid web of mineral fibres through which is substantially uniformly distributed a particulate endothermic material which has a mean particle size above 5 µm and is bonded to the mineral fibres of the web and is a material which is a carbonate and/or hydrate and which is heat stable at up to 200 °C and decomposes endothermically at a temperature above 200 °C.
La présente invention concerne un produit de protection contre le feu et les températures élevées, en l'occurrence un non-tissé de fibres minérales formé par voie pneumatique dans lequel est uniformément réparti un matériau granulaire dont les grains sont d'une grosseur moyenne supérieure à 5 m et sont agglomérés aux fibres minérales, ledit matériau granulaire étant un carbonate ou/et un hydrate thermostable jusqu'à une température de 200 oC, au-delà de laquelle il se décompose en donnant lieu à une réaction endothermique.
