Refractory high temperature 99% alumina ceramic fiberboard

The Refractory Ceramic Fiber Board is a specialized, high-performance rigid
insulation engineered for the most demanding thermal environments. As a type
of ceramic fiber board, it is manufactured through a precise vacuum-forming
process that combines high-purity alumino-silicate fibers with inorganic
binders. This creates a smooth-faced, dimensionally stable slab with a typical
density of 280–400 kg/m³. Designed to withstand continuous use at 1000°C and
short-term peaks up to 1260°C, it offers a unique combination of low thermal
conductivity, minimal heat storage, and exceptional resistance to thermal
shock. Sunjoy provides this high-quality refractory solution, backed by
extensive customization options to meet your exact specifications.
Refractory Ceramic Fiber Board Advantages
Lightweight & Rigid: With a density significantly lower than firebrick, it is
easy to handle, cut, and install, while maintaining excellent structural
integrity for vertical and overhead applications.
Superior Thermal Insulation: Its ultra-low thermal conductivity (as low as
0.12 W/(m·K) at 600°C) effectively blocks heat transfer, reducing energy
consumption and lowering equipment surface temperatures for safer operation.
