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 FormsLow Thermal ConductivityHighly RefractoryNon-RCF FibersLow Shrinkage up to 1500°C97% Pure AluminaAvailable “Off the Shelf”Information provided by Zircar Zirconia.
