Foamfrax® Insulation, a monolithic insulation system, is a three-component system of specially conditioned bulk ceramic or soluble fibers, an inorganic binder, and an organic foaming binder. The installation process combines the bulk fiber material with the inorganic and organic binders in a patented mixing mechanism creating a homogeneous foam/fiber mixture. The Foamfrax installation machinery propels this mixture through a feed hose and nozzle, and the material is then gunned onto the target surface. The proprietary Foamfrax binder system and patented installation method completely encapsulate the fibers with the foaming binder, significantly reducing airborne fiber levels during installation.
Foamfrax Insulation is available in the following fiber grades:
Foamfrax Grade I Fiber (2300°F Refractory Ceramic Fiber)
Foamfrax Grade II Fiber (2600°F Refractory Ceramic Fiber)
Foamfrax Grade III Fiber (3000°F Polycrystalline Mullite Fiber)
Isofoam™ Fiber (2300°F Soluble Fiber)
The interlocking network of fibers provides a strong, uniform monolithic structure having excellent thermal insulating properties, very low heat storage, and excellent resistance to thermal shock.
Foamfrax Insulation is used to insulate metal, refractory, or ceramic fiber surfaces at temperatures up to 2450°F. It can be installed at rates in excess of 1000 board feet/hr and is used in a wide range of furnace lining and other insulating applications. A principal application of Foamfrax Insulation is to upgrade the efficiency of partially deteriorated furnace linings. The rapid application of several inches of Foamfrax Insulation onto the existing hot face surface extends the furnace lining life and improves furnace efficiency. Foamfrax Insulation can also be installed as a full-thickness system by using stainless steel anchors which are embedded within the Foamfrax Insulation to retain the furnace lining.
