Pyro-Log Fiber & Pyro-Packing (2400ºF – 2600ºF Range)

Raw material for all Pyro-Bloc modules, Pyro-Log fiber is manufactured from a high purity blend of raw materials which are used to produce R Grade (alumina-silica), ZR Grade (alumina-zirconia-silica), and C Grade (alumina-silica-chromia) edge grained ceramic fiber blocks of varying sizes ancell nameensities.
