SuperMag-HI™ is a high-temperature blanket insulation, with a high fiber index and a low percentage of unfiberized particles. Manufactured from a proprietary blend of calcium, silica and magnesium oxides, it is a low bio-persistent fiber, with superior mechanical and insulation properties for use temperature to 1,200 °C (2,200 °F).

Completely inorganic, SuperMag-HI™, produces zero smoke or outgassing when exposed to high temperature. The high fiber index and elimination of large unfiberized particles gives SuperMag-HI™ superior insulation, low thermal conductivity values.

Finer fiber diameters combined with the elimination, of course, unfeberized particles gives SuperMag-HI™ a softer hand, greater flexibility and higher strength, with low dust irritation making it the ideal choice for fabricated products.
