Product Description

Definition:

Refers to the high porosity (40% ~ 85%), bulk density low (usually less than 1.3 g/cm3) refractory materials.

Features:

1.Low thermal conductivity, relatively dense stomatic distribution has good heat insulation effect,

2. Low thermal capacity: in the case of absorb more heat, brick itself very little heat, energy saving effect is obvious.

3.Low impurity content, has a very low iron and alkali metal melt less impurity in low temperature.

4.High dimensional accuracy, mechanical processing molding,

5.High precision and can be processed into special shape, speed up the building.
