Thermal Insulation Brick

Detailed Product Description

The photo shows JM insulating brick, the type is JM28.

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, JAPAN etc. Our brand is CCE WOOL, and OEM is also accepted.

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.
