CERAMIC FIBER BOARD
Description:
Ceramic fiber boards are manufactured in a wet vacuum forming process by blending the chopped ceramic fiber with inorganic or organic binders for excellent abrasive resistance at high temperature.
Ceramic fiber board feature low thermal conductivity, high thermal stability and excellent thermal shock resistance.
The products are classified as STD, HP, HA and Hz respectively corresponding to different maximum service temperature 1000º C, 1100º C, 1200º C and 1350º C.
Applications:
Hot air duct lining
Shuttle kiln with high gas velocity
Laboratory furnace
Kiln car insulation
Die-cut high temperature seal
Advantages:
Low heat storage
Low thermal conductivity
Excellent abrasive resistance
Excellent thermal shock resistance
Excellent chemical stability
Even density and thickness
Specification(mm):600*400*20-50;900*600*20-50,other made according to customers's requirement.
