ZRCI Refractory Sheet Type RS-101 is a ceramic fiber reinforced structural alumina product with useful properties to 2300°F (1260°C). It retains strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos-cement replacements. Type RS-101 not only makes an excellent replacement for rigid asbestos containing products, but also may be employed at much higher temperatures as well. Type RS-101 is 100% inorganic, non-flammable and contains no asbestos. Its high Al2O3 content makes it resistant to many environments including no outgassing on heating, is not brittle, and may be cut and machined with standard tooling. Type RS-101 is available in standard and custom size cylinders.
