3M Nextel™ 550 Industrial Ceramic Fiber
Subcategory: Oxide, Silicon; Oxide, Aluminum; Oxide; Composite Fibers
Key Words: Alumina, Aluminum Oxide
Material Notes: Chemical composition above is wt%. Crystal phases are gamma alumina amorphous SiO2. Filament diameter is 10-12 µm. 3M Nextel fibers 312, 440, and 550 are designed for non-structural applications where their primary purpose is to act as a flame barrier. 3M Nextel Ceramic Fiber 550 is made from Al2O3, SiO2, and B2O3. Because 550 does not contain B2O3, this composition retains its strength better at high temperature. Information provided by 3M Ceramic Textile and Composites.
