Excelfrax(r) microporous insulation is composed of inorganic oxides, primarily fused silica. Silicates and opacifiers are added to improve the material performance. Microporous insulation products actually have thermal conductivity value lower than still air due to its ability of to block conduction, convection and radiation. The Excelfrax(r) product line offers a number of advantages including low thermal conductivity, thermal stability, consistent operating temperatures and easy fabrication. The low thermal conductivity of Excelfrax(r) allows users to save space, reduce weight and increase operational efficiency. Excelfrax(r) is manufactured exclusively for Unifrax by Wacker Chemie GmbH and is a registered trademark of Unifrax Corporation.
