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.
