Introduction:
Ceramic fiber blanket is made from bulk fibers, produced by the most modern spinning needling and thermal forming processes. Ceramic fiber blanket consists of a group of thermally efficient high temperature insulating materials that combine the advantages of both low heat storage and complete resistance to thermal shock.
 
Features:
1.Low thermal conductivity. 
2.Good thermal shock resistance. 
3.Excellent chemical stability. 
4.Low shot content. 
5.Low heat storage. 
 
Application:
It can be used for industrial furnace lining ,high temperature pipes heat preserve,heat resistant sealing gasket,glass tank furnace thermal insulation,power boiler and nuclear heat insulation and ceramics kilns thermal insulation.
