RS-100 Boards | ZIRCAR Refractory Composites, Inc.

General Info

ZIRCAR Refractory Sheet Type RS-100 is a ceramic fiber reinforced structural alumina composite material with useful properties to 1260°C (2300°F). It has exceptional flexural and compressive strengths in the range of high temperature reinforced plastics such as G-7 and G-10 laminates and retains strength and utility to levels far exceeding maximum use temperatures of plastics. Mechanical properties of Type RS-100 sheet far exceed those of asbestos-cement materials and it is an excellent replacement for these rigid asbestos-containing products. Type RS-100 can also be employed at much higher temperatures than these types of products.

Type RS-100 is 100% inorganic, non-flammable and contains no asbestos. Its high Al₂O₃ content makes it highly resistant to many environments, including molten aluminum. It undergoes little or no outgassing on heating. It is not brittle and has high impact properties. Type RS-100 may be cut and machined with standard tooling. Type 100 sheet is used both as a full-size panel and as a source for precision-cut fabricated components.

Refractory Sheet Material is available in Cylinder form asRefractory Sheet Type RS-101 Cylinders.

SUGGESTED APPLICATIONS

Type RS-100 is the ideal asbestos-cement board replacement.
Type RS-100 is ideal for specialty furnace components such as bottom supports for quartz furnaces, furnace shells with element feed throughs and low temperature kiln and oven walls.
Type RS-100 is used as Induction furnace components such as channel melter components, coil liners, coreless induction components, covers, tops, bases, front and back plates, coil supports, splash and coil shields.
Type RS-100 is use in Non-ferrous metal handling as spouts, troughs, and casting tips
Type RS-100 is the ideal material for use as electrical terminal blocks and electrical resistor grids, due to its good electrical resistivity, good mechanical strength and its ability to withstand temperatures to 1260°C (2300°F).
Type RS-100 is used as an electrical insulator for induction pressing of diamond saw segments.
Type RS-100 is used for brazing separators and fixtures. The high Al2O3 content makes it resistant to sticking in many environments including molten metals.
Type RS-100 is used in the glass industry as dead plates, set out plates, wear guides and pusher pads in hot glass handling.
