Refractory Sheet Boards Type RSBD-LD, RSBD-HD, RSBD-240, RSBD-400 are rigid, high temperature ceramic bodies. They are available in various temperature use and mechanical strength ranges. They feature excellent insulating performance, good high temperature strength and can be custom designed for a broad range of uses. Types RSBD-LD and RSBD-HD are rated for use up to 1260°C (2300°F) and types RSBD-240 and RSBD-400 are rated for use up to 1650°C (3000°F). They are manufactured using Alumina and Alumina Silica fibers and high temperature inorganic binders. RSBD-LD, RSBD-HD, and RSBD-240 are manufactured with a small amount of additional organic binder which is added to the board formulation for increased handling strength. Where present, the organic binder will burn out at temperatures between 232°C (450°F) to 316°C (600°F) during initial heat up by the end user. Following burnout the boards are white in color. RSBD-400 is pre-fired and will not smoke or outgas when heated. They are white as received. The homogeneous microstructure and consistent binder distribution allow this material to be machined to tight exacting tolerances with ordinary shop tools and equipment. Their superior machinability and dimensional stability plus low heat capacity make them ideal for use as setters, supports and process fixtures in both continuous and batch firing furnaces. Properties Unique Properties Include: Low thermal conductivity High temperature stability Uniform density Excellent resistance to thermal shock Excellent chemical stability, resisting attack by most corrosive agents.
