Morgan Advanced Ceramics Pyro-Log Fiber and Pyro Packaging C Grade Thermal Ceramic
Categories: Ceramic; Oxide

Material Notes: Pyro-Log is an uncompressed monolithic mass of ceramic fiber. Pyro-Log fiber is available in 6" and 8" (152 mm and 203 mm) thicknesses with densities up to 15 pcf (240 kg/m3 ). Manufactured in three ceramic fiber 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. This lubricant also adds pliability which allows true multi-directional compression during installation. At moderate temperatures this lubricant burns out and the fiber mass becomes rigid. This feature, unique to Pyro-Log fiber, assists during installation and provides the durability and toughness necessary for long life.
