ALFISO VACUUM FORMED BOARD GENERAL INFORMATION ALFISO boards are high performance insulation products manufactured from ceramic fiber and binders, with ALFISO’s unique shot removing and vacuum forming process, provide excellent high temperature stability, extra low thermal conductivity, high compressive strength. ALFISO boards can be easy to saw, drill and die-cut, used as hot-face or back-up thermal insulation in various high temperature applications in furnaces, kilns etc. Additional hardness and strength can be reached with post treatments. Available in variety compositions, densities, sizes and post treatments combinations, ALFISO board is one of the most versatile products available to the industry today. ALFISO 1260/300 board is a self-supporting product available in a variety of sizes and thicknesses for general duty insulation. It can be produced in different strength ranges to fit individual applications. ALFISO 1300/420 board is a high strength product for applications where tough mechanical stress resistance is required, ideal for back-up insulation behind dense refractories. ALFISO 1400/300 board is made from high alumina ceramic fiber and binders, non-wetting to molten aluminum metal and exhibits good resistance to chemical attack. ALFISO 1400/650 board is high strength product made from high alumina ceramic fiber, fillers and binders, with very high compressive and flexural strengths, with non-wetting to molten aluminum metal and exhibits good resistance to chemical attack. ALFISO 1430/300 board is made from alumina–silica- zirconia fiber, exhibits low shrinkage, low thermal conductivity, low heat storage at elevated temperatures and high performance of thermal shock resistance.
