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.
