Unifrax Fiberfrax® Moist Pak-D® Ceramic Fiber Insulator

Fiberfrax Moist Pak-D insulation is made from high-strength ceramic fiber blankets impregnated with inorganic bonding agents. This processing results in a flexible insulation that air dries to form a hard, rigid structure. Moist Pak-D is ideal for insulation of complex shapes and for service under conditions of high hot gas velocities.The material is packaged in a clear polyethylene bag to retain the wet binder during shipment and storage. Since damage will occur, care should be taken to prevent freezing of the product.Curing of product can be accomplished by air drying for several days or by immediate exposure to temperature in the application. Curing is merely a function of removing the water from the inorganic binder.Typical ApplicationsHot face layer for Fiberfrax heater, furnace and kiln linings where hot gas velocities exceed 12.2 m/sec (40 ft/sec)Hot gas duct, flue and stack liningsRecuperator liningsBlow pipe liningsExternal and internal pipe insulationReformer header insulationProcess furnace tube weld protectionThermal and corrosion protection of process heater tube supportsInformation Provided by Unifrax I LLC
