| Fiberfrax® Duraboard® products are a family of rigid, high-temperature ceramic fiber boards manufactured in a wet forming process using Fiberfrax alumina-silica fibers and binders. All Duraboard products offer low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock and chemical attack. Duraboard 3000 insulation, the highest temperature rated board manufactured by Unifrax, provides maximum high-temperature stability and shrinkage resistance. Also formulated from a blend of Fiberfrax alumina-silica fibers and Fibermax, Unifrax's patented polycrystalline mullite fibers, Duraboard 3000 insulation derives its exceptional high-temperature capability from an increased Fibermax fiber concentration in the blend. This unique formulation controls shrinkage to a level of only 1.2% after 168 hours at 2700°F / 1482°C. Description: Formed from a special blend of Fiberfrax alumina-silica fibers and Fibermax® Mullite fibers. These boards give high stability at temperatures up to 2700°F / 1482°C.
