Unifrax Excelfrax® 1800 Flexliner Microporous Insulation
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Unifrax Corporation's Excelfrax® product line, based on advanced microporous insulation technology, is a family of products which all exhibit superior insulating characteristics. Excelfrax microporous insulation is composed of inorganic oxides, primarily fumed silica. Silicates and opacifiers are added to improve the material performance. Microporous materials are very efficient insulation products. These products actually have thermal conductivity values lower than still air.

Excelfrax 1800 Flexliner is a flexible, thin, microporous insulating panel with superior insulating characteristics. Excelfrax 1800 Flexliner is designed for use between the ladle shell and backup lining. This product can be used to provide maximum thermal efficiency in ladle liner design. By incorporating Excelfrax 1800 Flexliner into a lining design, it is possible to reduce ladle heat loss without decreasing ladle capacity, increase ladle capacity by reducing required thickness of insulating materials, and minimize the amount of solidified metal in the ladle after the casting process is complete. Typical applications for Excelfrax 1800 Flexliner include transfer ladles, torpedo ladles, and tundish insulation.
