The present invention provides a composition comprising at least 15 weight percent of a polymer based composition comprising at least 50 weight percent of an organic polymer based on the total weight of the composition; At least 15% silicate mineral filler based on the total weight of the composition; And at least one source of at least one fluxing oxide optionally present in the silicate mineral filler, wherein the molten oxide is present in an amount of from 1% to 15% by weight of the residue after exposure to high temperatures experienced in a fire condition. A refractory composition for forming a refractory ceramic at a high temperature present, wherein the refractory composition is useful for passive fire protection applications, the molten oxide is present in 1 to 15% by weight of the residue. |
