General Info
ZIRCAR Refractory Sheet Type RS-1200 is a high strength composite designed for use as thermo-mechanical and electrical insulation in applications with temperatures as high as 1300°C(2372°F). RS-1200 is a combination of strong reinforcing fibers tightly bound in an alumina ceramic matrix. RS-1200 is completely inorganic and contains no asbestos or RCF fibers. RS-1200 exhibits greater refractoriness and homogeneity than other reinforced alumina matrix composite products and can be readily machined to tight tolerances with conventional carbide tooling.
