| Unifrax Corporation's Excelfrax® 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 Board is a high-temperature, rigid, microporous material specifically designed for applications where a strong, highly efficient insulating material is required. Excelfrax 1800 Board is available in thicknesses up to 2" and can be field fabricated to meet specific appliation requirements. Some typical applications for Excelfrax 1800 Board include back-up insulation in high-temperature furnaces (steel, glass, ceramic, aluminum), aluminum launders, and aluminum transfer ladles.
