Thermfrax® Gemcolite® AASIL FG30-11000 is Unifrax Engineered Thermal Component’s (UETC) High-alumina, high-temperature insulation board. It is composed of man-made vitreous alumina to provide a very high temperature board with minimal shrinkage and low density. It is best used in applications with extreme high temperature, up to 1648°C (3000°F), where minimal board weight is needed, or where the application is silica sensitive. It has a low shot content and high vibration resistance. Gemcolite® AASIL FG30-11000 resists thermal shock allowing for faster cycle times. UETC’s vast forming and machining capabilities allow Gemcolite® AASIL FG30-11000 to be made in a variety of shapes, besides standard boards and blocks, and can be tailor made to customer required shapes and specifications. This material is also easily cut and formed using hand-tools.
