refractory ceramic fiber blankets

CERAMIC FIBER BLANKETS   NR blankets are made from selected high quality spun ceramic fiber, double sides mechanically needling makes it high strength and surface integrity   NR blankets have a good character of superior insulating performance, light weight, flexibility, resilience and chemical resistance, low thermal conductivity, low heat storage,                         Available Density and Size   Density: 4, 6, 8 lbs./cu. ft. (64, 96, 128 kg/m3) Thickness: 1/2", 1", 1-1/2", 2" (12.5mm, 25mm, 38mm, 50mm) Width: 24" and 48" (610mm and  1220mm) Packaging: In plastic bags and then in cartons      Characteristics   Double needled blanket  Low density  Low thermal conductivity  Shorter heat up and cool down time  Resilience and resistance to thermal shock  Flexible and easy to cut and install  Contain no organic binder  Asbestos free   TYPICAL APPLICATIONS   Flexible high temperature pipe insulation and casting mold insulation. Repair, insulation and linings for furnaces, kilns, ovens, generators, reformers, boilers, High temperature pipe insulation, duct and turbine insulation. Forging Furnaces linings. High-temperature seals and gasketing, furnace door seals Glass furnace crown insulation.
