Unifrax rigid board products are manufactured to provide excellent performance in any application, which requires high modulus of rupture (MOR) and a rigid form. The product is designed to resist erosion, vibration, mechanical stress, and can be easily customized on jobs to fit any installation.Working temperature goes up to 1650°C and most to the products has good chemical resistance.
Fiberfrax Duraboard – products are a family of rigid, high-temperature ceramic fibre boards manufactured in a wet forming process using Fiberfrax alumina-silicate fibers and binders. All Duraboard products offer low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock and chemical attack. Fiberfrax Duraboard products exhibit thermal stability at temperatures up to 1650°C.
Insulfrax Blok are produced using a combination of mineral wool and Insulfrax alkaline earth silicate wool mixed with specially selected inorganic and organic binders to achieve outstanding performance. Insulfrax Blok is specially designed for use as an additional insulation in various high temperature applications in the industry. Insulfrax Blok is available in two stages, the Blok 80 is suitable for applications with operating temperatures up to 800 ° C and 110 Blok for applications with operating temperatures up to 1100 ° C.
Insulfrax Boards are manufactured from Insulfrax alkaline earth silicate wool, mixed with specially selected inorganic and organic binders, to produce a solid “base” with outstanding characteristics. The 110ZK is easy to cut and trim with standard tools. These “base” exhibits high strength and hardness combined with excellent insulation performance and high temperature stability. 110LD is particularly suitable for precision machining applications. Insulfrax Boards are available in a wide range of sizes and thicknesses.
