SuperMag HI 2200 low biopersistent fiber

SuperMag HI 2200

Low Biopersistence Fiber Blankets

SuperMag HI 2200 blankets are made from long strand spun, fine low bio-persistence (LBP) fibers with lower shot content forming a flexible needled product with high strength and superior thermal properties at temperatures up to 2200°F (1200°C), while offering lower thermal conductivity, less dust and reduced risk of irritation.

The strong needling of SuperMag HI 2200 blankets results in a completely inorganic, binder-free product that produces no smoke/outgassing.

SuperMag HI 2200 is available in a range of thicknesses and densities.
