Unifrax Engineered Thermal Component’s (UETC) Thermfrax® T-Cast® All-alumina Insulation material specially designed for fuel cell applications. It uses high-purity alumina in a special process that minimizes silica content and ensures superb mechanical and chemical properties that allow it to survive reducing atmospheres as in a majority of Solid Oxide Fuel Cell units and Hydrogen Furnaces. It is also useful wherever a robust high-temperature insulation is required. Thermfrax® T-Cast® has superb strength and mechanical properties, and the density is tightly controlled in three ranges. UETC’s vast forming and machining capabilities allow Thermfrax® T-Cast® to be made in a variety of shapes, besides standard boards and blocks, and can be tailor made to customer required shapes and specifications.
