MSDS | Technical Data Sheet

Versatile industrial insulating materials for 2300ºF applications

Gemcolite® products are formed using alumina-silicate fibers and include both inorganic and organic binders for excellent handling strength and material integrity at high temperatures. Gemcolite® is suitable for applications up to 1260°C (2300°F).

Manufacturing Capabilities

Gemcolite® can be formed as boards, sleeves, combustion chambers and any custom shape. In addition, Refractory Specialties has a wide range of machining capabilities for added details and tight tolerances. Insulation Boards may be surface treated to provide additional erosion or chemical resistance for use in hostile environments. Gemcolite® materials can have hardware molded or installed into them to provide easy installation.

Excellent Energy Conservation

Low thermal conductivity and heat storage make Gemcolite® materials an outstanding energy saver. Thermal shock resistance permits fast thermal cycling without cracking or spalling.

Applications include:

  • Boiler and Water heater linings for combustion areas
  • Pipe insulation
  • Gasketing
  • Heat Shielding
  • Fire Protection
  • Kiln and Industrial furnace linings
  • Flue liners
  • Backup insulation for castables, brick, etc.
  • Burner assemblies, and nozzles
  • Usable anywhere high temperature insulation is required
