OVERVIEW of Fiberfrax-Duraboard |
Fiberfrax® Duraboard® products are a family of rigid, high temperature
ceramic fiber boards manufactured in a wet forming
process using Fiberfrax alumina-silica fibers and binders.
All Duraboard products offer low thermal conductivity, high
temperature stability, uniform density, and excellent resistance
to thermal shock and chemical attack.
They are also well-suited for applications experiencing
vibration, mechanical stress and strong erosive forces. The
excellent rigidity and modulus of rupture possessed by these
boards makes them strong and self-supporting, yet relatively
lightweight and easy to cut or machine.

FEATURES AND BENEFITS of Fiberfrax-Duraboard |
2300°F Rated Grades:
14-24 - A rolled, rigidized surface finish and high MOR give a tough, economic refractory grade product.
16-20 - A higher quality surface finish and tighter dimensional tolerances make this board suitable
for use in situations where aesthetic quality, as well as performance, is important.
23-27 - The addition of clay gives a higher density, MOR, and strength.
18-21 - Unique family of highly machinable lightweight boards manufactured with three to four times
the green strength as standard board products.
2600°F Rated Grades:
10-14 - Formed from a special blend of regular Fiberfrax alumina-silica fibers and Fibermax® Mullite
fibers. These boards give high stability at temperatures up to 2450°F and 1343°F.
3000°F Rated Grades:
9-12 - Formed from a special blend of regular Fiberfrax alumina silica fibers and Fibermax Mullite
fibers. These boards give high stability at temperatures up to 2700°F and 1482°F.
