3R 2300
CERAMIC FIBER BLANKET
ISO 9001 : 2000 Certified
 

The ceramic fiber blankets are produced from exceptionnally pure oxides of alumina and silica using the spinning process. The 3R 2300 blankets offer excellent handling ability and high temperature stability which allows it to meet a wide range of hot face and back up insulation applications in furnaces, kilns and other equipment requiring high temperature heat containment.
 

Applications //
The ceramic fiber blankets applications are numerous. They are used as furnace linings, boiler combustion chambers, heat exchangers, gas turbines, high temperature fan insulation, removable insulating pads on steam valves and separators. They are used as oven linings, superheated seals, stress relief pads, expansion joints packing and many more. Especially recommended for those applications requiring a low iron content of less than 1% and for highly reducing atmosphere.
