CERAMIC FIBER BOARDS
We offer high temperature ceramic Fiber boards, which are produced through wet forming process of ceramic fiber and binders. The ceramic Fiber boards are featured with high temperature stability, low thermal conductivity, even density, and excellent resistance against thermal shock and chemical attack. The ceramic Fiber boards also resist oxidation and reduction. If they are wet by water, steam, or oil, physical and thermal properties are fully restored upon drying. Ceramic Fiber boards are used for a baffle and muffles, heat shields, combustion chambers, flue insulation, and fire protection. These boards are available in available in a variety of temperature ratings, densities, thickness, widths and lengths, and custom vacuum formed shapes.
