The C-Cast® product line was developed specifically for applications where refractory fiber alone rapidly degrades. It boasts superior chemical and abrasion resistance when compared to other ceramic fiber formulations.
C-Cast® products are formed using a composite of alumina-silicate fibers, high performance components, and include both inorganic and organic binders for excellent handling strength and material integrity at high temperatures. C-Cast® is suitable for applications up to 1260°C (2300°F).
C-Cast® can be formed as boards, sleeves, 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 specific chemical resistance for use in extremely hostile environments. C-Cast® materials can have hardware molded or installed into them to provide easy installation.
Low thermal conductivity and heat storage make C-Cast® materials an outstanding energy saver. Thermal shock resistance permits fast cycling without cracking or spalling.
