Product 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 insulatio and ceramics kilns thermal insulation.
