polycrystalline mullite fiber boards are manufactured in a wet forming process using alumina-silica fibers and binders. Lower thermal conductivity, superior mechanical properties and high-temperature stability offer unmatched performance reliability.They can help reduce energy costs and cycling times once being installed in furnace ,boiler lining. If wet by water, steam or oil, thermal and physical properties are 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°F/232°C to 600°F/316°C during initial heat up by the end user. Following burnout of the organic binder, the boards are white in color.
