ZIRCAR Refractory Composites, Inc. produces a comprehensive range of advanced high performance ceramic-ceramic
composites and related products. Our materials are used around the world in demanding thermal, structural and
electrical insulating applications at temperatures from 600°C(1112°F) to 1650°C(3002°F). For over twenty-five years we
have been a problem solver working with many industries to resolve their thermal management problems. We have
developed materials that have become industry standards for induction melting, forging and heat-treating applications,
investment casting, glass processing, hot pressing, as well as many high temperature electrical applications.
Refractory Sheet Types RS-100 and RS-200 boards
are fiber reinforced structural Alumina composites with
useful properties in thermal, structural and electrical
insulation applications to 1260°C(2300°F). Type RS-
100 has compressive and flexural strengths in the range
of high temperature reinforced plastics, such as G-10
laminates, but retains its strength and utility to levels far
exceeding the maximum use temperatures of plastics.
The mechanical properties of RS-100 exceed those of all
calcium-silicate materials, as well as Transite and other
asbestos cement materials, overall temperature ranges.
Therefore, Type RS-100 not only makes an excellent
replacement for rigid asbestos-containing products, but it
can also be employed at much higher temperatures. Type
RS-100 is 100% inorganic, non-flammable and contains
no asbestos. It's high Alumina content makes it highly
resistant to many environments, including molten
aluminum, and it undergoes no out-gassing upon heating.
It is not brittle and has high impact resistance. Type RS-
100 may be cut and machined with standard tooling.
Type RS-200 boards have all the properties of Type RS-
100 but exhibit higher strength due to a finer reinforcement
structure. This makes Type RS-200 ideal for applications
where intricate machining detail is needed. It is not brittle
and has high impact resistance. Type RS-200 may be cut
and machined with standard tooling.
ZIRCAR Refractory Sheet Type RS-1200 boards are
made from a combination of strong reinforcing fibers tightly
bound in an alumina ceramic matrix. Type RS-1200 exhibits
slightly lower compressive and flexural strength than RS-
100. Type RS-1200 is completely inorganic and contains
no asbestos or RCF fibers. It also exhibits greater
refractoriness and homogeneity than other reinforced
alumina matrix composite products and can be readily
machined to tight tolerances with conventional carbide
tooling.
