Unifrax Fibermax® Duraboard® 18R Board

Duraboard® 1700 and Duraboard® 1800 are an extension to the Fibermax® product line. These board products exhibit excellent thermal stability (low shrinkage) at very high operating temperatures. Another benefit of these board products is their extremely high modulus of rupture (MOR) in both the green and fired state. Because of their strength, both Duraboard 1700 and Duraboard 1800 are very well suited for applications where sag resistance is critical. Duraboard 17R and 18R have a rolled finish, while Duraboard 17H and 18H are compressed during manufacturing for optimum density and sanded smooth. Standard thicknesses available for these products are 13mm, 25mm, 38mm, and 50mm.Typical ApplicationsHigh-temperature laboratory furnaces/kilnsDiffusion FurnacesKiln setter tilesSpecialty shapesAtmosphere furnacesElectric furnacesInformation Provided by Unifrax I LLC
