Fiberfrax^® Duraboard^® 350ES

Fiberfrax^® Duraboard^® 350ES products use a unique fiber formulation to obtain high strength and machinability not normally achieved in lightweight ceramic fiber board products. 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.
