Material Notes:
Fiberfrax® LTC HSA™ Systems is a ceramic fiber insulation constructed from multiple layers of ceramic fiber paper encapsulated between an outer covering of high-temperature woven textile cloth and parallel stitched to form a flexible insulation pad.The thermal resistance properties exhibited by LTC HSA Systems are a result of the lightweight ceramic fiber paper core material composed of fine diameter fibers. This core paper has a small cell structure; in addition, all unfiberized particles have been eliminated. This results in very low thermal conductivity and good high-temperature insulation values. The high fiber index results in high resistance to mechanical and acoustical vibration. If wet by water or steam, all LTC HSA System's thermal and physical properties are restored upon drying. It also exhibits excellent chemical stability and resistance to attack from most corrosive agents. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalies. Key performance features of LTC HSA Systems include:Very low thermal conductivityLightweightHigh-temperature insulating valuesExcellent vibration resistanceUnaffected by moistureSuperior flexural integrityApplications: The lightweight, excellent thermal and vibration resistance of LTC HSA Systems allow it to provide maximum insulating value while utilizing the least amount of weight and space. These features make LTC HSA Systems an idea choice for high-performance applications where critical areas are exposed to high operating temperatures, high vibration environments or are at risk from potential fire damage. Typical high-performance applications include:Heat shield insulation on missiles, rockets and space exploration equipmentThermal insulation on commercial and military aircraft - engine struts, thrust reversers, nacellesInsulation liners for fire protection of hazardous material storage containersExpansion joints for engine and turbine exhaust ductsInformation Provided by Unifrax I LLC
