Morgan Advanced Ceramics Cerafelt Refractory Fiber Felt
Categories: Ceramic; Oxide

Material Notes: Cerafelt™ is an insulating refractory felt, obtained by hot pressing. It is made from Cerachem fibers, bonded with an organic binder which begins to burn out at 180°C. This special binder makes Cerafelt particularly suitable for die-cutting operations. Semi rigid, it is neither brittle nor dusty. Cerafelt optimizes the manufacture of complex, die-cut shapes to close tolerances. With a choice from eight densities and seven thicknesses, Cerafelt offers a grade to suit most requirements. Made from chemically stables fibers, lightweight and very insulating, Cerafelt is a multi-purpose product.

Applications:

  • High temperature gaskets
  • Expansion joints for furnace, kiln and boiler linings
  • Die cut shapes for domestic appliances
  • Thermal barrier media
  • Insulating thermal break
