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