Material Notes:
ZRCI Refractory Sheet Type RS-200 is a fiber-reinforced ceramic laminate with useful properties to 1260°C (2300°F). This high temperature product offers high strength, moderate thermal conductivity and excellent electrical insulation. It retains its strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos cement replacements. RS-200 is 100% inorganic, non-flammable and contains no asbestos. Its high alumina content makes it resistant to many environments including molten aluminum. RS-200 undergoes little or no outgassing on heating, is not brittle, and may be cut and machined with standard tooling. RS-200 is available in standard and custom boards and is useful as Specialty Furnace Components, Specialty High Temperature Electrical Thermal Insulation, Metal Working Components and Induction Furnace Components.Information provided by ZIRCAR Refractory Composites, Inc.
