DESCRIPTION
Fiberfrax® Durablanket family of lightweight needled blankets are
manufactured from Fiberfrax® refractory ceramic fibres and provide
effective solutions to a variety of thermal management applications.
Fiberfrax® Durablanket products offer superior insulating performance,
excellent chemical resistance, flexibility and resilience. Fiberfrax®
Durablanket products are completely inorganic and so retain their
strength, flexibility and thermal properties in many working environments,
without the generation of smoke or fumes. Available in a wide range of
density and thickness combinations, Fiberfrax® Durablanket range is one
of the most versatile available in the market today.
GENERAL CHARACTERISTICS
Fiberfrax® Durablanket has the following outstanding characteristics :
Low thermal conductivity & heat storage
Resistance to thermal shock & chemical attack
High heat reflectance
Good sound absorption
Low shrinkage
High tensile strength & resiliency
Asbestos free
Unlimited shelf life
TYPICAL APPLICATIONS
CPI heaters & heat treatment furnaces
High temperature pipe, duct & turbine insulation
Boilers, kilns & ovens insulations
Tube seals, gaskets & expansion joints
Fire protection & acoustic insulation
Any new and/or special use of these products, whether or not in an application listed in our literature, must be
