The Fiberfrax® Durablanket family of lightweight needled blankets are manufactured from Fiberfrax® refractory ceramic fibres and provide effective solutions to a variety of thermal management problems. 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.
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
• CPI heaters & heat treatment furnaces
• High temperature pipe, duct & turbine insulation
• Boiler, kilns & ovens insulations
• Tube seals, gaskets & expansion joints
• Fire protection & acoustic insulation
FIBERFRAX® DURABLANKET Z
Fiberfrax® Durablanket Z is a high temperature blanket made from spun Zirconia stabilised ceramic fibre. It is a highly efficient insulator with extremely low shrinkage characteristics at elevated temperatures, low heat storage capacity and complete resistance to damage from is ideally suited to use in high temperature furnace lining systems.
Individual data sheets are available for the other products in the Durablanket range
Thermal Conductivity figures are empirical values (average)
based on experience.
Tolerances as per ASTM C-892 (2010) or IS 15402 (2003). Classification Temperature is not a definition of the operational limit of these products, especially when long term physical or dimensional stability is a factor. For certain applications continuous use temperature limits may be significantly reduced.
