Foamfrax HD Insulation is a four-component system of specially conditioned bulk ceramic fibers, an inorganic binder, an organic foaming binder, and a clay additive.
Foamfrax HD Insulation is available in three fiber grades: Foamfrax HD Grade I Fiber (2300˚F Refractory Ceramic Fiber), Foamfrax HD Grade II (2600˚F Refractory Ceramic Fiber), and Foamfrax HD Grade III (2800˚F Refractory Ceramic Fiber).
Foamfrax HD is easily installed. 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 HD Insulation is unaffected by most chemicals except hydrofluoric acid, phosphoric acid, and concentrated alkalies. Foamfrax HD is used to insulate metal refractory, or ceramic fiber surfaces at temperatures up to 2800˚F. It can be installed at rates several times faster than conventional insulating products, to solve a wide range of thermal management problems. A principal application of Foamfrax HD Insulation is to make high-strength ceramic fiber shapes using the Foamfrax process. This method features extremely quick fabrication and inexpensivee mold design. Foamfrax HD Insulation has the following outstanding characteristics:
- Speed and ease of installation
- Low rebound
- Low thermal conductivity
- Low thermal shrinkage
- Low heat storage
- Excellent thermal shock resistance
- Good chemical resistance
- Good sound absorption
