Material Notes:
Foamfrax® HD Insulation is a monolithic thermal management product developed by Unifrax Corporation. This product is a four-component system of specially conditioned bulk ceramic fibers, an inorganic binder, an organic foaming binder, and a clay additive. Foamfrax HD is easily installed. The interlocking network of fibers provides a strong, uniform monolithic structure having excellent thermal insulating properties, very low heat storage, and excellent resistance to thermal shock. Foamfrax HD Insulation is unaffected by most chemicals except hydrofluoric acid, phosphoric acid, and concentrated alkalies.CharacteristicsSpeed and ease of installationLow reboundLow thermal conductivityLow thermal shrinkageLow heat storageExcellent thermal shock resistanceGood chemical resistanceGood sound absorptionPrincipal ApplicationsFurnace linings (reformers, boilers, kilns, heat treating furnaces, etc.)Vessel liningsIncinerators, flues, ducts and stacksLow mass kiln car decksHigh-velocity applicationsComposite lining systemsRefractory shapesInformation Provided by Unifrax I LLC
