SIBREX®140

The soft boards of a volumetric weight of 140 kg/m3 are used predominantly in technological parts of structures for the insulation of unprotected and slightly curved surfaces.

Due to high temperatures, the organic binder burns out, partially reducing the board consistency and strength. For this reason, the organic binder is combined with an inorganic one, as even a small quantity of inorganic binder improves the board consistency considerably in heat, although it does not reach the consistency level of boards bonded solely with inorganic binders. SIBREX®140 boards can be used advantageously as thermal insulation for the protection of structures against high temperatures and heat dissipation, e.g. for the insulation of air heaters, blast and glass furnaces, etc. High energy economies are achieved in all applications, especially in cyclically working equipment, where considerably lower heat accumulation in comparison with conventional lining applies in addition to the board insulation properties. The boards can be glued to existing ceramic furnace lining by means of Soudal refractory or stove-making putty (commonly available from paint and varnish retailers).
