Ceramic Fiber Millboard

CeramSource offers a premium-grade, thin, dense ceramic fiber millboard product, which has excellent insulating properties and compression strengths throughout its temperature use range. Our ceramic fiber millboard is produced in a unique, continuous board – manufacturing process from a blend of ceramic fibers, clay, insert fillers, and a small amount of organic/inorganic binders for increased handling strengths. Ceramic fiber millboard maintains its strength and thermal stability throughout a wide temperature range up to 2300 ºF. Our ceramic fiber millboard has close thickness and dimensional tolerances, and is easily die-cut. These features make our ceramic fiber millboard an excellent choice for many gasketing applications in a wide range of industries and applications. The high density and compressive resistance make our ceramic fiber millboard an ideal product for refractory backup insulation, as compared to lower density vacuum formed boards or more compressible paper products.
