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 Celsius. These polycrystalline fiber blankets offer higher temperature capability, less shrinkage and greater chemical resistance than standard alumina-silica blankets.

Buster Mat exhibits lower thermal conductivity, lower thermal mass and greater thermal shock resistance than all alumina-silica blankets, while also providing a much cleaner insulation. The minor addition of silica modifies the alumina fiber's microcrystalline structure and acts as a grain growth inhibitor and prevents embrittlement that usually occurs in pure alumina after extended use at elevated temperatures. Buster Mat resists attack in aggressive chemical environments due to its high purity & refractory nature. It is stable in vacuum, inert, oxidizing or reducing atmospheres.

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.
