REFRACTORY SHEET TYPE RS-200

(PDF VERSION)

GENERAL INFORMATION
ZRCI Refractory Sheet Type RS-200 is a fiber-reinforced ceramic laminate with useful properties to 1260C (2300F). This high temperature product offers high strength, moderate thermal conductivity and excellent electrical insulation. It retains its strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos cement replacements. RS-200 is 100% inorganic, non-flammable and contains no asbestos. Its high alumina content makes it resistant to many environments including molten aluminum. RS-200 undergoes little or no outgassing on heating, is not brittle, and may be cut and machined with standard tooling. RS-200 is available in standard and custom boards and is useful as Specialty Furnace Components, Specialty High Temperature Electrical Thermal Insulation, Metal Working Components and Induction Furnace Components.

Compared to ZRCI Refractory Sheet Type RS-100 , RS-200 has the following attributes:

  • Finer reinforcement structure which allows for machining of intricate detail
  • Less tendency to delaminate
  • Higher strength

Refractory Sheet Type RS-200 material is available in Cylinder form as Refractory Sheet Cylinders Type RS-201.

SUGGESTED APPLICATIONS

  • Type RS-200 is the ideal TransiteTM and asbestos-cement board replacement.

  • Type RS-200 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-200 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-200 is use in Non-ferrous metal handling as spouts, troughs, and casting tips.

  • Type RS-200 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 1260C (2300F).

  • Type RS-200 is used as an electrical insulator for induction pressing of diamond saw segments.

  • Type RS-200 is used for Brazing separators and fixtures. The high Al2O3 content makes it resistant to sticking in many environments including molten metals.

  • Type RS-200 is used in the glass industry as dead plates, set out plates, wear guides and pusher pads in hot glass handling.
