ALUMINA COMPOSITESRS-100, RS-200, RS-1200, RS-101, RS-201, and RS-202 Refractory Sheet Types RS-100 and RS-200 boards are fiber reinforced structural alumina composites with useful properties in thermal, structural and electrical insulation applications to 1260°C(2300°F). Refractory Sheet Type RS- 100 has compressive and flexural strengths in the range of high temperature reinforced plastics, such as G-10 laminates, but retains its strength and utility to levels far exceeding the maximum use temperatures of plastics. Mechanical properties of Type RS-100 sheet far exceed those of asbestos-cement materials and is an excellent replacement for these rigid asbestos-containing products. Therefore, Type RS-100 not only makes an excellent replacement for rigid asbestos-containing products, but it can also be employed at much higher temperatures. Type RS-100 is 100% inorganic, non-flammable and contains no asbestos or Refractory Ceramic Fiber (RCF). Its high alumina content makes it highly resistant to many environments, including molten aluminum, and it undergoes no out-gassing upon heating. It is not brittle and has high impact resistance. Type RS- 100 may be cut and machined with standard tooling. Refractory Sheet Type RS-200 boards have all the properties of Type RS- 100 but exhibit higher strength due to a finer reinforcement structure. This makes Type RS-200 ideal for applications where intricate machining detail is needed. It is not brittle and has high impact resistance. Type RS-200 may be cut and machined with standard tooling. Refractory Sheet Type RS-1200 boards are made from a combination of strong reinforcing fibers tightly bound in an alumina ceramic matrix. Type RS-1200 exhibits slightly lower compressive and flexural strength than RS-100. Type RS-1200 is completely inorganic and contains no asbestos or RCF fibers. It also exhibits greater refractoriness and homogeneity than other reinforced alumina matrix composite products and can be readily machined with conventional carbide tooling. • Induction Furnace Components such as Coil Support Posts, Coil Liners, Furnace Tops, Crucible Bases, Front and Back Plates • Electrical Terminal Blocks and Supports for Electrical Resistor Grids Operating in High Temperature Environments • Exterior Structural Insulation in High Temperature Electrically Heated and Gas Fired Furnaces • Hot Face Structural Insulation in Glass Tempering and Annealing Furnaces • Brazing Separators and Fixtures • General Protective Heat Shielding in Foundry Environments • Insulation in High Pressure Molding Presses • Hearth plates and Furnace Shelving Technical Data ZIRCAR Refractory Composites, Inc.
