Zirconia ceramic fibre boards and various custom-shaped products are high-performance thermal insulation materials designed for use in extreme high-temperature environments where conventional insulation fails. These products are manufactured using stabilized zirconium oxide fibers, offering exceptional resistance to heat, thermal shock, and chemical corrosion. Capable of withstanding continuous operating temperatures up to 1650°C and peak exposures up to 1800°C, zirconia ceramic fibre boards provide outstanding thermal insulation with remarkably low thermal conductivity and low heat storage.

These boards are lightweight yet dimensionally stable, even under thermal cycling and in reducing or oxidizing atmospheres. The material is non-combustible, non-reactive, and possesses excellent resistance to molten metals, slags, and aggressive gases, making it an ideal choice for lining high-temperature furnaces, kilns, incinerators, and reactors in industries such as aerospace, metallurgy, ceramics, and glass.

In addition to standard boards, a wide range of custom-shaped zirconia ceramic fibre products can be fabricated based on specific client requirements. These include vacuum-formed shapes, rings, tubes, insulating plugs, and precision-molded components used in complex thermal management systems. Custom parts maintain the same performance characteristics as the boards and are engineered to ensure perfect fit and insulation efficiency in tightly constrained or uniquely shaped systems.

Whether used as thermal linings, structural insulation, or heat shields, zirconia ceramic fibre boards and custom-shaped products offer superior reliability, energy efficiency, and extended service life in even the harshest thermal conditions. Their ability to reduce energy loss, improve thermal uniformity, and maintain performance across thermal cycles makes them an essential material in advanced industrial applications.
