Fiberfrax Ceramic Fiber PapersArmil CFS offers several grades of Fiberfrax ceramic fiber papers for a variety of applications. All Fiberfrax papers are thin, flexible insulation materials consisting primarily of a matrix of alumino-silicate fiber with a latex binding system.

Fiberfrax 440 papers are a lower cost, composite made from a combination of ceramic fiber, inert fillers, and fiberglass reinforcement. The fiberglass gives 440 papers added strength at operating temperatures between 450°F and 1300°F. 440 Paper also contains a fire-retardant smoke suppressant. 440 paper is available in 1/8” thickness (Fiberfrax 440J Paper).

Fiberfrax 550 paper is made from unwashed high purity Fiberfrax ceramic fiber. Fiberfrax 550 paper is commonly used in gasketing, sealing, and refractory back-up applications. Fiberfrax 550 paper is available in 1/16” thickness (Fiberfrax 550F paper), 1/8” (Fiberfrax 550 J paper), and ¼” thickness (Fiberfrax 550K paper)

Fiberfrax 970 paper is made from washed high purity Fiberfrax ceramic fibers. The washing process removes unfiberized particles from the fiber, leaving a paper with improved uniformity and thermal performance. This “cleaner” paper extends die life in die stamping operations where unfiberized particles cause increased wear on dies. Fiberfrax 970 paper is available in 1/32” (Fiberfrax 970 A paper), 1/16” (Fiberfrax 970F paper), and 1/8” (Fiberfrax 970 J paper) thicknesses.

Fiberfrax 880 paper is made from higher alumina that fibers laid up at higher densities. This gives 880 paper a higher temperature grade (2600°F) then the other Fiberfrax papers. Fiberfrax 880 paper is available in 1/16” (Fiberfrax 880F paper) and 1/8” (Fiberfrax 880J paper).

Fiberfrax 880 and 970 papers are also available without the organic binder systems. Both 882-H and 972-H papers are heat treated during the manufacturing process to remove organics.

Fiberfrax Rollboard is a lower density ceramic fiber that offers more flexibility. Fiberfrax Rollboard is a good choice for wrapping intricate shapes or molds or in single use applications.
