CERAMIC FIBER BOARDS

 

 

Classification Temperature

• COM Ceramic Blown fiber Blanket 1260° C (2300° F)
• STD Ceramic Blown fiber Blanket 1260° C (2300° F)
• HP Ceramic Blown fiber Blanket 1260° C (2300° F)
• HA Ceramic Blown fiber Blanket 1400° C (2550° F)

Production Technology

• Each type of ceramic fiber board is made up from corresponding blowing fiber, common (COM), standard (STD), high alumina (HA), high purity (HP) or zirconia (HZ). They are produced by vacuum forming technology.
• The ceramic fiber boards have hard texture, excellent toughness and intensity, and excellent erosion resistance.

Working Temperature

• Working Temperature depends on working condition, heating method and environment atmosphere, etc.

Characteristics

• Low thermal conductivity
• Low heat storage
• Excellent chemical stability
• Excellent toughness
• Excellent erosion resistance
• Excellent processing function

Usage

• Liners of industrial furnace
• High temperature equipment insulation
