Refractory High Temperature 99% Alumina Ceramic Fiberboard - China
price: contact company for price
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 provide s this high-quality refractory solution, backed by extensive customization options to meet your exact specifications.
