The ceramic fibers are composed of :
   - ceramic fibres (between 2 and 4 microns) with a maximum length of 50 mm
   - support fibers composed of viscose or polyester and a frame either of glass (silionne) or nickel chrome

Principal characteristics :
   - High temperature resistance (static use) Excellent potential for thermal and electrical isolation (glass frame)
   - Very good resistance to chemical agents (except fluorohydric acid, phosphoric and concentrated bases)
   - Total absence of chlorine
   - Good resistance to molten aluminum and zinc.

Chemical composition :

Al2O3	45 - 50 %
SiO2	48 - 53 %
Fe2O3	0,7 - 1,2 %
