Ceramic fiber bulk

Product description:
RACOFIBER™ ceramic fiber bulk is made by melting the raw material from the resistance furnace and then blown or spun into fibers. It’s a kind of fibers in bulk and without any secondary process and thermal treatment. Depends on the requirement of the customers ,  it can be made into ceramic fiber chopped bulk. 
 
Features:
Low thermal conductivity and capacity .
Good chemical stability
Good thermal stability
Without binding agent and corrosive material
Good sound absorbing performance .

Application:
Power boiler, steam turbine and the insulating of the nuclear power.
The wall lining of the high temperature reaction and heating equipment in chemical industry.
The fireproof and thermal insulation of the high-rise structure.
Furnace insulation
High temperature filter material
The padding of the complex framework.
