General Info

LUMINAR FUSING SHEET  Type RS-100 is an a reinforced structural alumina composite material, heat treated to enhance mechanical and thermal properties. It is ideal for slumping and fusing projects to 860°C(1550°F) and can be used up to 1260°C(2300°F) as a electrical and thermal barrier. 

It has a smooth burnished surface that glass will not stick to. It is lighter than other fully dense kiln shelf materials and allows for rapid heating and cooling cycles. The LUMINAR FUSING SHEET can be fired repeatedly (its tan color will turn white on first firing) and can be cut to the desired size with standard saws or other common tool. 

To prevent warping or slumping of the sheet when firing heavy loads, some support should be provided from below. It is available in many thicknesses.

LUMINAR FUSING SHEET is 100% inorganic, non-flammable and contains no asbestos. Its high Al2O3 content makes it highly resistant to many environments, including molten glass and bronz.

Instructions

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.
