Fiberfrax 970 Paper is made from washed high-purity ceramic fibers. Since most of the unfiberized particles are removed, this paper is more uniform & offers improved thermal performance.
Fiberfrax 880 Paper is made from higher alumina ceramic fibers at a higher density. Besides an increased operating temperature range, it also offers reduced shrinkage & better chemical resistivity.
is manufactured from the 880 Paper. 882 Paper is heat treated during the manufacturing process to remove organic binders. It has the maximum burn strength of any unbindered paper.
Fiberfrax 972 Paper is made from high purity washed ceramic fibers. 972 Paper has a considerable portion of the unfiberized particles removed prior to the paper lay-up. In addition, 972 Paper is heat treated during the manufacturing process to remove organic binders. It remains soft & flexible.
