Refractory Sheet Board Type RSBD-LD and Type RSBD-HD are rigid, high temperature ceramic fiber boards manufactured in a wet forming process using aluminasilica fibers and binders. They are rated to 1260°C (2300°F) and have densities of 0.26 g/cc (16 pcf) and 0.46 g/cc (25 pcf). They offer low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock and chemical attack. Type RSBD-HD's higher density and strength make it wellsuited for applications experiencing vibration, mechanical stress and strong erosive forces. The excellent rigidity and modulus of rupture possessed by the RSBD-HD makes it strong and self-supporting, yet relatively lightweight and easy to cut or machine. This allows for quick, efficient handling and high installation rates, thereby enabling fast turnaround times in a variety of industrial insulation applications. Type RSBD-LD exhibits similar properties, but is lower in density and has lower thermal conductivity. These materials exhibit excellent chemical stability, resisting attack by most corrosive agents. Exceptions are hydrofluoric, phosphoric, hydrochloric and sulfuric acids, as well as concentrated alkalies. If wet by water, steam or oil, thermal and physical
