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 this 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.

DURABOARD 2600:
Duraboard 2600 insulation is a high-temperature insulating board designed to provide high stability at elevated temperatures. This capability is achieved by manufacturing a board formulated with a blend of Fiberfrax® alumina-silica fibers and Fibermax, Unifrax Corporation’s patented polycrystalline mullite fibers. This unique formulation controls thermal shrinkage to a level less than 1.0% after 168 hours at 2450°F.

DURABOARD 3000:
Duraboard 3000 insulation, the highest temperature rated board manufactured by Unifrax Corporation, provides maximum high-temperature stability and shrinkage resistance. Also, formulated from a blend of Fiberfrax alumina-silica fibers and Fibermax, Unifrax Corporation’s patented polycrystalline mullite fibers, Duraboard 3000 insulation derives its exceptional high-temperature capability from an increased Fibermax fiber concentration in the blend. This unique formulation controls shrinkage to a level of only 1.2% after 168 hours at 1482°C (2700°F). 

DURABOARD 350ES & 500ES:

The innovative composite binder system using both inorganic and organic components results in a strength-to-weight ratio of more than three times that of standard refractory ceramic fiber boards. Improved physical characteristics of these products allow for easier handling and fabrication.

Duraboard 350ES has more than three times the strength of standard boards of similar densities and thicknesses. Duraboard 500ES has more than four times the strength of standard boards of similar densities and thicknesses.

DURABOARD HD & LD:
Duraboard HD insulation is a high-density board product that offers the same high level of dimensional and surface uniformity as Duraboard LD insulation, but provides enhanced compressive strengh and a higher modulus of rupture. This higher density is achieved through the inclusion of clay additives during the manufacturing process.

Its higher strength makes Duraboard HD insulation particularly well-suited to weight load support applications such as refractory brick backup or for covering larger unsupported spans.

DURABOARD RG:
Duraboard RG (Refractory Grade) insulation is a cost-effective insulating board manufactured with the specific requirements of the refractory industry in mind. It has a rolled, rigidized surface which gives it a high modulus of rupture and compressive strength as well as high abrasion and hot gas erosion resistance.

These properties make Duraboard RG insulation ideally suited for use both as a backup to dense refractories, such as those used in the glass industry, and as a hot face protective layer over blanket linings where the rigidized surface aids in dust suppression during both installation and operation.
