SPUN FIBER BLANKET

 

 

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)
• HZ Ceramic Blown fiber Blanket 1400° C(2550° F)

Production Technology

• Each type of Ceramic Fiber Blanket is made up of the corresponding ceramic fiber, common (COM), standard (STD), high alimina (HA), high purity (HP) , or zirconia (HZ) fiber which is produced by spinning technology.
• Blankets are available in a variety of bulk weight and thickness. The blankets are well constructed with even distribution and flat surface and offer high tensile strength.

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 thermal stability and thermal shock resistance
• Excellent tensile strength
• Excellent sound absorption
