Thermal Ceramics Pyro-Log C Fiber
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Pyro-Log is an uncompressed monolithic mass of ceramic fiber. Pyro-Log fiber is available in 6" and 8" (152 mm to 203 mm) thicknesses with densities up to 15 pcf (240 kg/m3). Manufactured in three temperature grades, R, ZR and C, the Pyro-Log fiber can be used in a wide range of applications. Pyro-Log fiber is the basic building block for all Pyro-Bloc applications.

All Pyro-Log fiber is produced with a special lubricant that allows the fibers to be intensely needled to attain densities up to 15 pcf (240 kg/m 3). This lubricant also adds pliability which allows true multidirectional compression during installation. At moderate temperatures this lubricant burns out and the fiber becomes rigid enough to stand on. This feature, unique to Pyro-Log fiber, assists during installation and provides the durability and toughness necessary for long life.
