ZIRCAR Refractory Sheet Type RS-99 is a moderatelyhigh-density fiber based ceramic material with greater than 99% Alumina purity. Refractory Sheet Type RS-99 is usable to temperatures of 1650°C (3002°F) and is able to withstand over 500 hours of continuous submersion inmolten aluminum at 750°C (1382°F) with no wetting and no degradation in properties. Type RS-99's high Alumina content is ideal for high vacuum, reducing atmospheres and other applications where silica cannot be tolerated, such as setters for P/M and MIM applications. Refractory Sheet Type RS-99 boards are available in three types: Type RS-99M is a plastic highly moldable sheet ideally suited for forming custom geometries or for molding in place.

Type RS-99W boards can be moistened with water and molded into any desired shape. After a low temperature bake-out of 300°C (570°F) the boards are unaffected by moisture.

Type RS-99R boards are prefired and are unaffected by moisture. They remain rigid even if saturated with water.

Suggested Applications

• High and Low Temperature Gasketing
• TransiteTM and Asbestos-Cement Board Replacement
• Dead Plates, Set Our Plates, Wear Guides and Pusher Pads in Hot Glass Handling
• Induction Furnace Components Such as; Channel Melter Components, Coil Liners, Coreless Induciton Components, Covers, Tops, Bases, Front and Back Plates, Coil Supports, Splash and Coil Shield
• Brazing Separators and Fixtures. the High Al2O3 Content Makes it Resistant to Sticking in Many Environments Including Molten Metals
• Rapid Cycle Furnance Door Cowls and Hot Face Supports
• Insulation in High Pressure Molding Presses
• High and Low Temperature Electrical Insulator

ZIRCAR Refractory Sheet Type RS-D is a group of medium density reinforced matrix composite products produced in a thin sheet form. Type RS-D is comprised of a high purity alumina matrix reinforced with high temperature ceramic fibers. Type RS-D has a maximum use temperature of 1200°C (2192°F) and is available in four forms, making it a versatile product useful in many applications. Type RS-D is also resistant to corrosion in numerous environments. Refractory Sheet Type RS-D are available in four Types:

• Refractory Sheet Type RS-DR

RS-DR is a rigid pre-fired sheet which has been heattreated to remove all organic binder rendering it stable to moisture attack. RS-DR can be readily machined to exacting dimensional tolerances with conventional tooling. It posseses high compressive and flexural strength and is therefore useful as a structural insulation material. Its high dielectric strength makes it suitable for use as a high temperature electrical insulation.

• Refractory Sheet Type RS-DD

RS-DD is a dried, rigid sheet which can be moistened with water to impart moldability. RS-DD can be molded into shape and dried. When exposed to a temperature of 300°C (570°F), it will become permanently rigid. At this point RS-DD will exhibit properties and characteristics similar to Type DR.

• Refractory Sheet Type RS-DM

RS-DM is a pre-moistened moldable Type D product. RS-DM is easily formed into complex shapes and can be dried and fired to impart high strength. RS-DM is ideally suited for use as a mold for slumping and fusing of glass.

• Refractory Sheet Type RS-DA

RS-DA is a moldable Type D product which exhibits lower density than RS-DM, making it highly moldable. Drying with subsequent heat treatment to 300°C will result in a permanently rigid structure.

Suggested Applications

• Asbestos cement board replacement
• Oven construction
• Induction heating lining and coil fixtures
• High temperature gasketing
• Molded shapes, tubes, trays, boats, etc. for sintering and heat-treating
• Art glass slumping ad fusing molds
• Heating element support
• Fireproof structural insulation
• Non-ferrous metal handling, spouts, troughts, casting tips
• Brazing separators and fixtures
• Hot furnace repairs
• Induction hot press insulation
