Morgan Advanced Ceramics Superwool® Boards and Shapes HT Thermal Ceramic
Categories: Ceramic; Oxide

Material Notes: AES Fiber Class. Superwool boards are processed from a slurry consisting of Superwool bulk fiber and organic binders. Each board has cut edges for controlled squareness and trueness. Boards may be ordered with both surfaces machined smooth to a close thickness tolerance. Superwool is a low bio-persistent fiber, manufactured from pure raw materials and processed to offer excellent performance in high-temperature applications. Superwool offers an alternative to traditional solutions due to its high refractoriness and excellent non-wetting characteristics with molten aluminum. Superwool provides stability and resistance to chemical attack. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalis (e.g. NaOH, KOH). Superwool is unaffected by incidental spills of oil or water. Thermal and physical properties are restored after drying. Superwool is ideally suited to individual applications and is available in a wide range of thicknesses and densities. The maximum continuous use temperature depends on the application.
