Material Notes:
Superwool boards are processed from a slurry consisting of Superwool bulk and organic binders. Each board has cut edges for controlled squareness and trueness. Boards up to 36” wide may be ordered with both surfaces machined smooth to a close thickness tolerance.Superwool provides stability and resistance to chemical attack. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalis (i.e. NaOH, KOH). Superwool is unaffected by incidental spills of oil or water. Thermal and physical properties are restored after drying.Superwool boards offer an excellent alternative for molten aluminum contact. Other applications include hot face furnace linings, backup insulation and trough linings for non-ferrous metals.Features: Rigid, self-supporting finer insulation Available in a variety of sizes and thicknesses Based on patented technology Reduces thickness of backup insulation up to 50% when replacing insulating firebrick or castables Low thermal conductivity and heat storage Non-wetting to molten aluminumApplications: Molten aluminum contact Furnace, kiln, and oven hot face linings Flue and chimney linings Insulation as backup to: firebrick, insulating firebrick, refractory castables, rammed shapes Appliance and heat processing insulationInformation provided by Thermal CeramicsData has not been recently verified.
