Ceramic Fiber Insulation Board for Industrial Furnaces
Mindelun ceramic fiber board is a rigid refractory insulation material developed for industrial thermal systems that require lightweight insulation and a stable panel structure. Made from alumina-silicate ceramic fibers with suitable binders, it provides low thermal conductivity, low heat storage and good thermal shock resistance under appropriate operating conditions.
With a standard classification temperature of 1260°C and common densities of 300–400 kg/m³, our ceramic fiber insulation board is suitable for various furnace lining, kiln insulation and heat-processing applications. Mindelun also offers custom dimensions and machining options to meet different equipment designs and installation requirements.
Main Features of Ceramic Fiber Board
- Thermal insulation performance: Helps minimize heat transfer and reduce energy loss in compatible industrial equipment.
- Rigid and lightweight panels: Suitable for flat lining surfaces, insulation barriers and prefabricated components.
- Low heat storage: Supports efficient thermal cycling in suitable furnace applications.
- Good thermal shock resistance: Designed to withstand temperature fluctuations within the recommended service range.
- Convenient fabrication: Can be cut to specified dimensions and processed into suitable shapes.
- Flexible customization: Special sizes, non-standard thicknesses and machined components can be discussed according to project requirements.
