Material Notes:
ZRCI Refractory Sheet Type RS-202 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 strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos cement replacements. It is 100% inorganic, non-flammable and contains no asbestos. Its high alumina content makes it resistant to many environments including molten aluminum. RS-202 undergoes little or no outgassing on heating, is not brittle, and may be cut and machined with standard tooling. RS-202 has an as formed surface. This is ideal when the OD is crucial for liner placement. It is available in standard and custom size cylinders and are useful as induction coil liners, induction furnace components, and molten metal transport tubes.Information provided by ZIRCAR Refractory Composites, Inc.
