Fiberfrax® Duraboard® LD products possess the same density and temperature rating as Duraboard® RG insulation, but is manufactured to tighter dimensional tolerances and has an excellent finished surface. These characteristics make it ideally suited for use as a sandwich or core material or for use in the manufacture of components where aesthetic quality, as well as uniformity and performance, is important. 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. They are also well-suited for applications experiencing vibration, mechanical stress and strong erosive forces. The excellent rigidity and modulus of rupture possessed by these boards makes them strong and self-supporting, yet relatively lightweight and easy-to cut or machine. These product features allow for quick, efficient handling and high installation rates, thereby enabling fast turnaround times in a variety of industrial insulation applications. Once installed, they can help reduce energy costs and cycling times due to their high insulating capability, as well as serving to protect refractory surfaces from thermal shock. 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. If wet by water, steam or oil, thermal and physical properties are completely restored upon drying. In order to provide handling strength during the manufacturing process, small quantities of organic and inorganic binders are typically added to the board formulation. Where present, the organic binding agents burn out at temperatures between 450 deg F/232 deg C to 600 deg F/316 deg C during initial heat up by the end user. Following burnout of the organic binder, the boards are white in color.
