High Strength Ceramic Fiber Board | Rigid, Wear-Resistant Board for Demanding Linings
Product Overview
High Strength Ceramic Fiber Board is the heavy-duty member of the ceramic fibre board range, built for positions where a lining has to carry load, resist abrasion and survive fast-moving hot gas. It is produced by wet-vacuum forming from high-purity alumina-silica fibre with a carefully balanced blend of inorganic and organic binders, then machined to size. The result is a rigid, self-supporting board with high compressive strength and a high modulus of rupture, so it can serve as a load-bearing panel rather than only as a soft insulation layer. Because the board is dense and uniform, with low shot content, it also resists erosion from high gas velocities and is non-wetting to molten aluminium and other non-ferrous metals. A small organic binder fraction provides cold strength and burns out cleanly at 200-300 C during the first firing, leaving the board white and dimensionally stable.
Key Features
High compressive strength and modulus of rupture: rigid and self-supporting, yet light enough to handle and machine easily.
Low thermal conductivity and low heat storage: cuts furnace energy use and shortens heat-up and cool-down cycles.
Excellent thermal shock resistance: rapid heating and cooling do not cause cracking or spalling.
Low shot content and even fibre: smooth faces, accurate dimensions and good flatness.
Erosion resistance: stands up to high gas velocities and most chemical attack, and molten aluminium does not wet it.
Asbestos-free, low organics: the binder burns out at 200-300 C, leaving a clean white board.

Application Scenarios
The board is specified for lining positions that combine heat, load and wear. Typical uses include furnace and kiln hot-face linings, backing insulation for brick and monolithic refractories, petrochemical, metallurgical and power-plant furnace walls and roofs, steel ladle, tundish and torpedo-car backup linings, glass tank insulation panels and burner blocks, combustion chambers in gas-fired boilers, high-temperature gaskets, seals and flame barriers, and ceramic shuttle, tunnel and roller kiln linings.
Factory & Service Advantages
We run the production line, the warehouse and the export packing ourselves, so buyers deal directly with the maker. Every High Strength Ceramic Fiber Board carries a batch ID linked to raw-material certificates, production parameters and inspection records, and each lot is released only after in-house testing for density, permanent linear change, thermal conductivity, compressive strength, modulus of rupture and chemical composition. Third-party verification through SGS, CE, REACH and AEO can be arranged on request. Standard sizes ship from ready stock, custom cut-outs, grooves and complex shapes are produced to drawing, and we regularly supply distributors and EPC contractors under confidential private-label agreements.
