Ceramic fiber blanket

Product description:

RACOFIBER™ ceramic fiber blanket select the high standard raw material ,after the melting of the resistance furnace and special needle process then molding  by high temperature treatment. It is applicable to different temperatures. It can be made into Alumina foiled ceramic fiber blanket according to the requirement of the customers.

Features:

Good extension strength. Continuous long fiber and double needled process guarantee the extension strength of the ceramic fiber blanket no matter before or after affected by the heat .
Good sound absorbing performance .
Excellent thermal shock resistance
Stretch flexible and elastic   

Application: 

The wall lining of the furnace, kiln roof insulation, furnace door sealing, flue lining
Duct insulation, the insulating of the internal components of the transport facilities
High temperature filter
