Insulating Brick

IFBs (Insulating Fire Brick) are particularly Suited to applications above 1000 °C  ,  where their thermal conductivity is as low as fiber based products , but with structural integrity Capable of dealing with erosive and abrasive environments. 

Features

1. Low thermal conductivity.

2.Excellent thermal insulation

3.Low density

4.Excellent thermal shock resistance

 

Typical Application 

Glass industry

Ceramics

Electric Aluminum industry

Heat surface fireproof lining

Iron & Steel industry

Non-ferrous metal industry
