ZIRCAR Refractory Sheet Type RS-100 is a ceramic fiber reinforced structural alumina composite material with useful properties to 1260°C (2300°F). It has exceptional flexural and compressive strengths in the range of high temperature reinforced plastics such as G-7 and G-10 laminates and retains strength and utility to levels far exceeding maximum use temperatures of plastics. Mechanical properties of Type RS-100 sheet far exceed those of TransiteTM and other asbestos-cement materials and is an excellent replacement for these rigid asbestos-containing products. Type RS-100 can also be employed at much higher temperatures than these types of products. Type RS-100 is 100% inorganic, non-flammable and contains no asbestos. Its high Al2O3 content makes it highly resistant to many environments, including molten aluminum. It undergoes little or no outgassing on heating. It is not brittle and has high impact properties. Type RS-100 may be cut and machined with standard tooling. Type 100 sheet is used both as a full-size panel and as a source for precision-cut fabricated components.
