Claims10
A flexible thermally insulative refractory composition suitable for use for the containment of molten material comprising, in approximate percentage by dry weight, 70 to 90% of an inorganic fiber and 10 to 30% of a material selected from the group consisting of asphalt, carbon black, graphite, silicon carbide, and furan resin.
A flexible thermally insulative refractory composition suitable for use for the containment of molten material comprising, in approximate percentage by dry weight, 70 to 85% of an inorganic fiber, 10 to 25% of a material selected from the group consisting of asphalt, carbon black, graphite, silicon carbide, and furan resin, and 2 to 10% of a phenolic resin.
A flexible thermally insulative refractory composition suitable for use for the containment of molten material comprising, in approximate percentage by dry weight, 70 to 85% of an inorganic fiber, 2 to 10% of a phenolic resin, 5 to 15% of a latex, 0.5 to 5% of an anionic polymer and 0.5 to 3.5% of a cationic polymer.
A flexible thermally insulative refractory composition suitable for use for the containment of molten material comprising, in approximate percentage by dry weight, 70 to 80% of an inorganic fiber, 10 to 15% of a material selected from the group consisting of asphalt, carbon black, graphite, silicon carbide, and furan resin, 4 to 6% of a phenolic resin, 5 to 10% of a latex, 0.5 to 4% of an anionic polymer and 0.5 to 2.5% of a cationic polymer.
