Material Notes:
Insulfrax S Blanket is a flexible, strong, lightweight, needled blanket produced from Insulfrax Fiber. Mechanical needling of the spun Insulfrax fibers eliminates the need for binders in the product's manufacture and results in a product with high tensile strength. Since Insulfrax S Blanket is completely inorganic, the product exhibits no smoke generation or outgassing in service.Insulfrax S Blanket combines low thermal conductivity with excellent resistance to thermal shock. Note that high humidity and wetting with water prior to service has little effect on Insulfrax S Blanket.A series of green dots on the surface of the blanket make identification, tracking, and inspection of Insulfrax S Blanket simple on the job site or in the fabrication shop.The Insulfrax Fiber calcium, magnesium, silicate chemistry provides superior wetting resistance to molten aluminum alloys. Testing with corrosive aluminum alloys at elevated temperatures has proven that Insulfrax fibers are superior to traditional alumina/silica refractory ceramic fibers.ApplicationsAppliances: Residential self-cleaning ovens; High-temperature commercial cooking appliancesHearth Products: Chimney insulationPrimary Metals: Expansion joint seals; Aluminum transfer ladle covers; Backup insulation for dense refractory linings; Backup insulation for refractory ceramic fiber or Isofrax® linings; Maintenance blanket; Heat shieldsMetals Processing: Stress relieving blankets; Seals and gasketsPetrochemical/Power: Reusable insulating pads; External boiler and duct insulationCeramic and Glass: Glass tank crown insulation; Expansion joints; Carbon baking furnace coversInformation Provided by Unifrax I LLC
