Fiberfrax® Duraboard® 2600 Insulation

Fiberfrax® Duraboard 2600 insulation is a high-temperature insulating board designed to provide high stability at elevated temperatures. This capability is achieved by manufacturing a board formulated with a blend of Fiberfrax® alumina-silica fibers and Fibermax®, Unifrax’s patented polycrystalline mullite fibers.

The Fiberfrax Duraboard family exhibits excellent chemical stability, resisting attack by most corrosive agents. Exceptions are hydrofluoric, phosphoric, hydrochloric and sulfuric acids as well as concentrated alkalies. Fiberfrax Duraboard products also resist oxidation and reduction.
