Pyrotek ISOMAG® 45 Thermal Insulation Board
Categories:	Ceramic; Oxide; Magnesium Oxide; Silicon Oxide
Material Notes:	Isomag® 45 is a medium density insulating board which provides excellent hot strength and insulating value. Its magnesia silicate based formulation provides insulating properties equivalent to calcium silicate boards, with superior dimensional stability. Incombustible, Isomag® 45 is totally free of asbestos and will not become wet by molten aluminum or its alloys. Applications Torpedo cars Tundishes Pellet stove covers Launder linings Distributor linings Trough covers Advantages Low heat loss at higher temperatures High temperature rating Low shrinkage at temperature use limit Asbestos free and ceramic fiber free Information provided by Pyrotek.
