Unifrax Foamfrax® Grade III Fiber Insulation

Foamfrax® Insulation is a monolithic insulation system developed by Unifrax. Foamfrax Insulation is a three-component system of specially conditioned bulk ceramic or soluble fibers, an inorganic binder, and an organic foaming binder. Foamfrax Insulation is easily installed at the job site by trained contractors using the special Foamfrax installation machinery. 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 Insulation is unaffected by most chemicals except hydrofluoric acid, phosphoric acid, and concentrated alkalies.CharacteristicsSpeed and ease of installationLow rebound during installationLow thermal conductivityLow thermal shrinkageLow heat storageExcellent thermal shock resistanceGood chemical resistanceGood sound absorptionPrincipal ApplicationsFurnace linings (reformers, boilers, kilns, heat treating furnaces, etc.)Vessel linings (incinerators, flues, ducts and stacks)Furnace refractory upgrades (Lining over Refractory (LOR), Fiber over Fiber (FOF))Low mass kiln car decksLadle preheat standsBackup for high-density gunned refractoriesBoiler tube wall insulationFurnace lining maintenance (gunning gaps, cracks and voids)Fire protectionInformation Provided by Unifrax I LLC
