Ceramic fiber blankets are made from high purity spun bulk wool, have the excellent chemical stability.

There are four kinds of ceramic fiber products according to the temperature and chemical content. They are STD(1260℃),HP(1260℃),HA(1350℃, high alumina),HZ(1430℃,contain ZrO2).

1) For the blanket, the bulk density will be 64kg/m3, 96 kg/m3, 128 kg/m3, 160 kg/m3.

2) For the paper, the bulk density will be 160-220 kg/m3.

3) For the board, the bulk density will be 240-400kg/m3.

Application

◆   Petrochemical process heater refractory fiber lining                           ◆ General furnace backup insulation

◆   Heat treating furnace or intermittent (shuttle) kiln hot face lining        ◆ Electrical insulator

◆   Heat seals for kiln car or furnace door                                                  ◆ High temperature acoustic   

◆ Fire protection

Classification Temperature

• COM Ceramic Blown fiber Blanket 1100° C (2012° 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 1430° C(2606° F)

They offer superior thermal insulation and refractory performance as well as acoustic characteristics. HP Blankets are unaffected by the most chemicals except hydrofluoric and phosphoric acids and strong alkalines.

They have excellent strength and mechanic properties before and after heating. Thermal and physical properties are retained after drying from oil, steam and water. 

 

Excellent insulating performance 

High tensile strength 

Excellent thermal stability 

Low heat storage 

Excellent thermal shock resistance 

Low thermal conductivity 

Good sound absorption
