Gemcolite®- No Smoke materials are formed using alumina-silicate fibers and inorganic binders. Refractory Specialties’ No-Smoke formulations are suitable for applications where the smoke from organic binder burnout is undesirable. The No-Smoke formulation is available as an option for most of Refractory Specialties’ Product lines.
Gemcolite®- NS 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®- NS materials can have hardware molded or installed into them to provide easy installation.
Low thermal conductivity and heat storage make Gemcolite®- NS materials an outstanding energy saver. Thermal shock resistance permits fast cycling without cracking or spalling.
