insulating brick

Detailed Product Description

The photo shows insulating brick coming out of the tunnel kiln. The red color tells us this is the chamotte insulating brick(light clay brick), NG series.

Double Egret is the specialized manufacturer and exporter of refracotry and insulation material in north of China. Our products mainly include insulating brick, refractory brick, refractory castable, ceramic fiber products. For insulating brick, the production capacity is 300tons per month, primarily export to UK, USA, ITALY, TURKEY, JAPAN etc.

JM insulating brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. JM insulating brick is the new energy saving material for insulation.
