„Effective Heat and Temperature Control“ is HOBRA’s comprehensive mark, under which all the company’s products and services in refractory and insulation applications are identified. In essence, it is a marketing project which covers everything HOBRA manufactures, offers and supplies in these spheres.
IZOBREX®refractory boards are manufactured from a mixture of ceramic aluminosilicate fibers and mineral wool, bonded with organic and inorganic binders. IZOBREX® refractory boards are intended especially for thermal insulation within the temperature range of 400-800°C.
The boards are manufactured in two types which differ in the basic mixture component proportion and the resulting different application temperature. For easier identification, the types of IZOBREX® boards are marked with colored bands:
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 board consistency in heat considerably, although it does not reach the consistency level of boards bonded solely with inorganic binders. IZOBREX® boards are used for thermal insulation in a number of products in power engineering, mechanical and electrical engineering, glass industry, for the insulation of cable systems and as part of fire -protection precautions in the technological sections of facilities and buildings. They are also used for thermal insulation of the lining of periodically working furnaces, boilers, etc.
The boards are manufactured using the paper-processing technology from a water suspension including suitable binders, aliminosilicate heat-resistant fibers and mineral wool in a suitable proportion.
IZOBREX® boards are used in the following applications:
