Thermfrax® Gemcolite® ASM FG30-115050 and FG30-165050 are Unifrax Engineered Thermal Component’s (UETC) high temperature insulation board. It uses man-made vitreous alumina silicate fibers enhanced with advanced high temperature fibers to provide very high temperature insulation with minimal shrinkage and high density and strength. It is best used in applications that necessitate extreme high temperature use, up to 1648°C (3000°F), and good board strength and resiliency. FG30-165050 is offered pre-fired to minimize shrinkage at extreme temperatures. UETC’s vast forming and machining capabilities allow Gemcolite® ASM 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.
