Zircar Zirconia Buster Blanket Alumina Blanket Insulation
Categories: Ceramic; Machinable Ceramic; Oxide; Aluminum Oxide

Material Notes: Buster Blanket and Buster Mat are flexible, Hi-Alpha alumina fiber insulation materials. The mat is 100% fibers while the blanket has been needled into a durable blanket with the addition of an organic fiber reinforcement. Both forms have useful properties up to 1600°C. These polycrystalline fiber blankets offer higher temperature capability, less shrinkage and greater chemical resistance than standard alumina-silica blankets. Buster Blanket is made by needling the Buster Mat with an organic fiber reinforcement. This additional processing results in a much denser, stronger and more durable flexible insulation. It is offered in both 1/2” and 1” standard thicknesses. Flexible Buster products are useful as insulation packing in furnace spaces, around furnace sight tubes & ports and as filler in expansion joints and masonry cracks.

Features:

  • Available in Two Different Forms
  • Low Thermal Conductivity
  • Highly Refractory
  • Non-RCF Fibers
  • Low Shrinkage up to 1500°C
  • 97% Pure Alumina
  • Available “Off the Shelf”
