SuperMag high temperatura insulation blankets are made from Nutec’s Low Bio-Persistent (LBP) fibers. These Spun fibers are needled into a blanket, resulting in a product with high strength and superior thermal properties at temperatures up to 2200°F (1200°C).
The superior needling eliminates the need for binders resulting in a completely inorganic blanket with no smoke generation or outgassing.
SuperMag high temperature insulation blankets can be a cost effective alternative to Refractory Ceramic Fiber (RCF) for applications to 2200°F (1200°C), that offers low thermal conductivity and minimal linear shrinkage.
SuperMag-HI offers the same temperature, but with much lower shot content and finer fiber diameters, resulting in lower thermal conductivity, and reduce dust and irritation.
Both grades are available in a range of thicknesses and densities.
