Insulating Fire Brick JM 30

Detailed Product Description

The photo shows JM insulating brick in wooden pallet pakage with thermal shrinkage film, and paper protect angle. This JM30 insulating brick has pure white color and is made in shuttle kiln at 1800^oC. The size is 230x114x65/75mm.

DOUBLE EGRET is the specialized manufacturer and exporter of insulation and refractory material in north of China with more than 10 years' history. Our brand CCE WOOL is well known in the world, enjoying good maket in Europe, America, Southeast Asia and Mid East.

CCE WOOL 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. We mainly export insulating brick to UK, USA, ITALY, JAPAN etc.

CHARACTERISTIC:

 Low thermal conductivity,excellent thermal insulation.

 Low thermal capacity excellent conserve energy in batchoperation kiln

 Low impurity. The higher aluminum content made it still to maintain good performance under the reducing atmosphere.
