Unifrax Foamfrax® Isofoam Fiber Insulation
Categories:	Ceramic; Oxide; Magnesium Oxide; Silicon Oxide
Material Notes:	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. Characteristics Speed and ease of installation Low rebound during installation Low thermal conductivity Low thermal shrinkage Low heat storage Excellent thermal shock resistance Good chemical resistance Good sound absorption Principal Applications Furnace 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 decks Ladle preheat stands Backup for high-density gunned refractories Boiler tube wall insulation Furnace lining maintenance (gunning gaps, cracks and voids) Fire protection Information Provided by Unifrax I LLC
