Fibermax® Duraboard® 1700 and Duraboard® 1800 are extensions 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 this strength, both Duraboard 1700 and Duraboard 1800 are very well-suited to applications where sag resistance is critical.
Additional offerings include Duraboard 17R and 18R, which have a rolled finish, while Duraboard 17H and 18H are compressed during manufacturing for optimum density and sanded smooth. The standard thicknesses available for these products are 13 mm (½”), 25 mm (1″), 38 mm (1½”) and 50 mm (2″). Also, if requested, these boards can be provided heat-treated to remove all organic content. Specialised shapes with similar product properties may be provided upon request.
