Fiberfrax® Duraboard® 1500 and 1600 are board products that demonstrate 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 1500 and Duraboard 1600 are very well-suited to applications where sag resistance is critical.
Fiberfrax® Duraboard® 1500 and 1600 have a rolled finish, and are compressed during manufacturing for optimum density before being 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.
