    Refractory Sheet Type RS-100 is available in 48 x 48 in. boards as a standard size. RS-100 is a fiber-reinforced structural Alumina composite with useful thermal, structural, and electrical insulating properties. These boards are also useful in the transport of molten non-ferrous metals to 2,300?F. 

     

    RS-100 has compressive and flexural strength in the range of high-temperature reinforced plastics such as G-10 laminates but retains its strength and utility far exceeding the maximum use of these materials. The mechanical properties of RS-100 exceed those of all calcium-silicate materials and asbestos cement materials over all temperature ranges. RS-100 makes an excellent replacement for rigid asbestos-containing products and can be employed at much higher temperatures.RS-100 is 100% inorganic, non-flammable, and contains no asbestos. 

     

    This material's high Alumina content makes RS-100 highly resistant to many environments, including non-ferrous metals, and it undergoes no out-gassing upon heating. RS-100 is not brittle and has high-impact properties. RS-100 may be cut and machined with standard tooling.
