GENERAL INFORMATION
General Information
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.
