chamotte insulating brick

Detailed Product Description

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 chamotte insulating brick is low density high porosity low thermal conductivity. Keep furnace wall low radiation and depress the charges of fuels.

CHARACTERISIC

Low thermal conductivity, excellent thermal insulation

Low thermal capacity excellent conserve energy in batch operation kiln

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

Precise outlook size. Speeds up the masonry and building speed, the brick work joint also neat is consistent. Guaranteed masonry and building body intensity high, the stability is high.

APPLICATION:

Heat surface fireproof lining or other fire-proof materials back lining thermal insulation
